Sentinel’s Commitment During Covid-19

Thank You!

Everyone across the country recognizes the importance of our First Responders during this unprecedented  Covid-19 pandemic. At Sentinel, we want to thank all First Responders for their courage and commitment, and specifically we want to recognize the law enforcement agencies we work with daily.

Throughout this pandemic Sentinel has collaborated with our customers and witnessed the extraordinary dedication you have towards community safety, officer safety, participant health, and implementation of COVID-19 risk reduction best practices. We have seen program populations expand while agencies continue to find creative ways to maintain participant supervision and social distancing guidelines. We have helped programs implement new technology designed to reduce participant foot traffic inside community correction offices and watched as local jails and Detention Centers implemented in-custody policies to reduce infection risks in their facilities.

While the individual and innovative changes that each of your programs has made may not make national news, we at Sentinel appreciate the efforts, professionalism and courage during these difficult times.

During this pandemic, we have adjusted our services and introduced new technology designed to limit direct participant contact while maintaining effective supervision levels. The expansion of our cell phone-based tracking options has allowed supervision to continue without the need for face to face meetings. Additionally, we have expanded product capacity to ensure our customers have access to the required monitoring devices and we are continuing to make sure certain devices are available for immediate shipment.

To learn more about how cell phone-based applications can be introduced within your program please contact Sentinel at 800-589-6003 ext. 2104 or https://www.sentineladvantage.com/contact-us/.

Thank you again for your commitment.

Survey seeks input from COs, facilities on steps taken during COVID-19 outbreak  

From the National Commission on Correctional Health Care:


Sentinel Offender Services continues to monitor and respond to the Coronavirus (COVID-19) outbreak for our customers. We have implemented several contingency measures to minimize disruption of service to customers and participants.  An important topic to begin addressing immediately is PREEMPTIVE RELEASE; Here is the direction from one of the websites we monitor:

In advance of the possibility of an increase in jail population, consider the efficacy of reducing your inmate population now. Work with your judiciary and prosecutors to mitigate existing sentences and/or obtain approval for the release of certain categories of inmates, such as civil infractions (child support, contempt of court, failure to pay fines, etc.), misdemeanants, probation violators and, possibly, non-violent felony offenders. This is not a “get out of jail free card,” but rather a proactive means of reducing your current population in preparation for what may come.


Sentinel can help prepare for PREEMPTIVE RELEASES. We have several tools that support community corrections for the tracking and reporting of offenders in the community.  Send an email to Sales@SentinelAdvantage.com. or request information  here

Domestic Violence: a National Epidemic

By | Blog, Uncategorized | No Comments


According to the National Coalition Against Domestic Violence,Domestic violence is the willful intimidation, physical assault, battery, sexual assault, and/or other abusive behavior as part of a systematic pattern of power and control perpetrated by one intimate partner against another .” Domestic violence is present in every community across America. It shows no favoritism or bias. It can happen anywhere. It cuts across all ethnic groups, economic classes, religions, sexual orientations, ages, and genders.

A Shocking Reality

Victims suffer from psychological trauma, physical abuse, and even death. What starts as emotional abuse often escalates physical violence.

…includes behaviors that physically harm, arouse fear, prevent a partner from doing what they wish; …includes the use of physical and sexual violence, threats and intimidation, emotional abuse …different forms of domestic violence/abuse can be occurring at any one time within the same intimate relationship.

  • Nearly 20 people per minute are physically abused by an intimate partner in the United States. More than 10 million a year *
  • 1 in 3 women and 1 in 4 men have experienced some form of physical violence by an intimate partner *
  • 1 in 7 women has been stalked. Stalking causes the target to fear they or someone close to them will be harmed or killed *

The impact extends beyond the targeted individual and affects the entire family. Even those who are just witnesses are severely impacted, especially children. This manifests as fear, anxiety, depression; self-abuse, hostility, and suicide. The damage can last a lifetime.*

Protection orders alone may not be enough to prevent an offender from re-assaulting a targeted individual.  All too often the offender returns to attack again. Being charged with a crime doesn’t stop them. The fact is, victims can be at risk at any time and place.

The following independent agencies advocate on behalf of victims, work for societal change, and can offer immediate help.

National Coalition Against Domestic Violence is a not for profit organization dedicated to supporting survivors, holding offenders accountable and supporting advocates. To get information or guidance for yourself or someone else they can be reached at  1-800-799-7233 or  https://ncadv.org/get-help.

National Domestic Violence Hotline provides lifesaving tools and immediate support to empower victims and survivors to find safety and live free of abuse; provide support to friends and family members who are concerned about a loved one. https://www.thehotline.org/help   1−800−799−7233

This information is offered as a public service for anyone seeking additional guidance on this matter. Sentinel does not offer an opinion and neither agrees or disagrees with specific positions of these organizations.  


Real-world tools to help in the fight


A Monitoring Program for Victims

Keeping the victim away from their attacker is an important step. When the violence stops, recovery can begin. We are proud that Sentinel Offender Services offers help to combat the problem. The Domestic Violence Monitoring program delivers the highest level of electronic monitoring that we offer and can have the greatest positive impact. In cooperation and coordination with local law enforcement agencies across the US thousands of victims and their attackers have been monitored through this program.

Victims sleep easier at night when they are in the program. They know that they will be alerted if the attacker gets too close. The program combines the services of our industry-leading National Monitoring Center with proven electronic monitoring technology and provides:

  • Simultaneous location tracking that compares the location of offenders and victims
  • Advanced notification to victims if a would-be assailant breaches an exclusion zone
  • Up-to-the-minute information to law enforcement to take appropriate action
  • 24 hour a day location monitoring that gives victims extra peace of mind in their daily lives

Participation in the program for the victim is entirely voluntary and is available with multiple levels of coverage.

Specific locations, such as the victim’s home or work, are identified as stationary exclusion zones and monitored 24 hour-a-day. Mobile Exclusion Zones are established to follow the victim as they travel throughout the community. When carrying a small GPS device, the area surrounding the victim -from hundreds of feet to tens of miles- is monitored 24 hours a day.

Should the offender breach any exclusion zone, specially trained operators in Sentinel’s 24/7 National Monitoring Center calmly notify the victim and law enforcement. They can then execute an appropriate safety plan. Law enforcement officials can take action. In every level of the program the victim is given advance notification of potential contact with the offender.


Programs for the Offender

When the offender stops offending, everyone wins. Sentinel delivers cognitive skills training  to help in this effort. Courses address the root causes of violence and provide tools to make better decisions. According to leading psychologists and criminologists, addressing the root causes of violence can help avoid it in the first place. Topics that are covered include:

  • Anger Management
  • Parenting and Family Values
  • Substance Abuse
  • Making Changes for Good

The courses work on cognitive restructuring. The offender develops self-awareness, self-control, and positive relationship management skills.

* “WHAT IS DOMESTIC VIOLENCE?”,  National Coalition Against Domestic Violence


By | Blog, Day Reporting Center, Reentry, Uncategorized | No Comments

Just a few blocks from the glitz and glamor of the Las Vegas strip sits a nondescript building. Every week hundreds of Nevadans on probation and parole come through the doors to prepare themselves to successfully re-enter the community as productive citizens.

On September 19, the DRC had its largest graduating group yet with 60 participants being recognized.

For the past two years, the Las Vegas Day Reporting Center has operated in partnership between Sentinel Offender Services and the Nevada Parole and Probation Division Since inception over 700 participants have participated in programs at the DRC. At any given time as many as 200 men and women are active.

Day Reporting Centers (DRC) are an important tool for community corrections.  As an alternative to incarceration and traditional parole and probation (P&P), the primary objective is to reduce recidivism; that is, to help offenders who are returning to society to stay out of jail. Probationers, referred to as ‘participants’ and not ‘offenders,’ benefit from programs that offer tools to become responsible, law-abiding citizens. The environment is more relaxed than a typical P&P office. This helps to promote personal development. What follows is a deeper relationship between the Probation and Parole Officer (PO) and the participant.

 One-stop shop

Rather than trying to juggle a schedule of meetings all across town and on different days, participants can complete nearly all ongoing requirements in one location. Centralizing the delivery of services is perhaps the most pragmatic feature of the DRC. This makes it easier to meet requirements and avoid technical violations. Technical violations can occur for a missed drug test or not attending a meeting. Just keeping track of appointments and getting around town can be a challenge for many. In a single visit, one can meet with their PO, take a drug test and attend required courses. If transportation is an issue, vouchers are available to pay for public transit.

Wrap-around services extend the value of the DRC. These are services that go a long way in helping participants stay on the path to success. Job coaching, housing assistance and securing support from the Department of Health and Human Services are available. Community partners offer 1-1 counseling onsite and a computer lab helps participants prepare for their GED. One can even acquire a new set of clothes from the onsite clothes pantry to dress for success during a job interview.

Changing behavior from the inside out

Every participant must complete Moral Reconation Therapy (MRT). MRT is a cognitive skills course that seeks to decrease recidivism with improved reasoning around criminogenic needs. Studies have shown that addressing criminogenic needs can reduce recidivism. This evidence-based program combines elements from a variety of psychological models to address moral, social, and positive behavioral topics.  Each week, more than 20 sessions of the course are offered.

Other courses that cover a wide range of topics are also available. Anger management, family and parenting, employment and education, and avoiding substance abuse are among the life skills which are taught. Participants set a custom curriculum to meet their unique needs.

Getting out of it what you put into it

Many graduates have turned their lives around. A few share their stories:

  • 2018 DRC Graduate

This program has changed my entire life. When I came here, I was homeless, I was broke, I didn’t have a job, I was sleeping in my car. I went through it all. But I was blessed to have a program to help me realize that I am somebody at the end of the day. Today I stand here in front of you as a restaurant manager. When I came here, I was nobody. If I can do it, you can do it.

“Every day, one day, one step; one day, one step; I get further and further toward my goals. It works. If you really want to change your life this is the place to come.”

  • March 2019 DRC Graduate

“I had an excuse for everything. I had to learn how to grow up…  I decided to do exactly what they tell me to do. It wasn’t always easy… Everything was a challenge… I started volunteering and ended up getting a job. I have been maintaining it and staying consistent. Consistency paid off for me.

“Be positive, keep a positive mind, speaking your world into existence… Keep believing in yourself. Don’t let anyone tell you that you can’t do anything… Do what you have to do right now so you can get where you want to be. It may sound hard but take it one step at a time.”

  • September 2019 DRC Graduate

“I’m given the opportunity to show that I can shine and be the person I’m not on paper. I was skeptical and hesitant when I started the MRT program. I realized that even though we have different stories, we have the same goal in the end: to better ourselves, be someone different or go back to be the person we once were.”

Producing measurable results

Everyone who completes MRT graduates. This is a big deal. The accomplishment is celebrated with peers, PO’s, family and friends.  Individual success stories are inspiring, yet as with most government programs, anecdotal success is not enough to ensure continued funding. The overall impact of the DRC must be quantified and documented. Fortunately, the Las Vegas DRC has generated positive results in multiple ways.

An independent research study by the University of Nevada at Las Vegas concluded that the DRC can reduce recidivism among at-risk parolees and probations. According to the study, DRC participants:

  • Were less likely to abscond (than those in general probation and parole)
  • Tended to have lower new charges and violations
  • Were significantly more likely to be successfully discharged
  • Were more likely to attain and maintain employment and a residence

Bottom-line impact:   Using the DRC as an alternative to incarceration saves taxpayer money. According to officials with the Nevada Department of Public Service, the DRC has saved the state approximately $3.8 million in the first 15 months of operation.

Commitment to personal success

On September 19, 2019 the DRC celebrated the largest graduation to date. At the event, Sergeant Shaira Chandler of Nevada Probation and Parole, the sergeant over the P&P unit at the DRC, shared insight into the unique relationship the program creates with participants.

“We just witnessed participants go from down and out to become productive citizens,” said Sgt. Chandler. She continued, “I want to see success in our participants. I want to see them thriving. I want to see them be the best they can be for themselves…  Participants come in after being done with the program and say ‘I want you to know I’m doing great. I want you to know you helped me.”


Good for the participant, good for the taxpayer, good for the community.

The Day Reporting Center is another Las Vegas winning story.

Criminogenic Risk and Reducing Recidivism

By | Blog, Day Reporting Center, Reentry, Uncategorized | No Comments

The National Institute of Justice (NIJ)  recently posted a description of recidivism. This included recidivism rates. The update summarizes statistics and provides useful insight. According to the report, 68% of offenders return to prison within three years. Within nine years, over 80% return to prison.

 According to Pew, twice as many people are in community corrections -4.5 million- as are in prisons and jails. Most of these folks will soon be part of the “rest” of society, about 9 out of 10 of them.  This general population of probation and parole is a revolving door of offenders going in and out of jail.  The recidivism rate is essentially flat over time, but many offenders go back to jail multiple times. This is happening while the number of people in community corrections programs has grown significantly.  The overall trend is going no where but slowly down.

Corrections agencies recognize that simply tracking and trying to keep probationers out of trouble is not enough. It is critical to help increase the chances that they will stay out of jail once they return to society.

Criminogenic Needs and Programs that Address Them

Beginning in the 1980s, research was done on how best to help offenders avoid returning to prison. Out of this research, a set of Criminogenic Needs emerged. These are risk factors or problem areas that can negatively impact the chance of reoffending.

According to several authorities in this field, including the National Institute of Health and National Council on Crime and Delinquency, there are an established “Big 8” criminogenic needs or factors:

  1. Antisocial beliefs; criminal orientation and thinking
  2. Antisocial associates or peer relationships
  3. Antisocial personality disorders and anger management
  4. Conviction history
  5. Family dysfunction, parenting and family relationships
  6. Education and employment
  7. Leisure and recreation
  8. Substance and alcohol abuse

Many organizations have successfully implemented evidence-based programs that address these risk factors head-on.  The objective of these programs is to reduce recidivism, improve reentry rates, and lower the cost of offender program management.

Sentinel Offender Services offers cognitive skills programs based on methodology proven to reduce recidivism. We have assisted several community corrections agencies in this effort. Together, we develop a custom curriculum designed to meet the needs of their specific offender population. Sentinel employees deliver end-to-end in-community programs.  Each course we deliver is built with evidence-based practices. Courses include anger management, thinking for good, parenting skills and similar.

Criminogenic Needs: The Risk of Returning to Prison

Getting Closer to Customers in 2019: Here we grow Again

By | Blog, Day Reporting Center, ELECTRONIC MONITORING, Reentry, Uncategorized | No Comments

Getting closer to customers is a strategic initiative for Sentinel Offender Services. We are doing this by opening new branch offices in communities across the country.  Since January we have opened three new offices. Each location allows us to deliver products, services. and community-based programs and get to know our customers on a more personalized basis.

Every Sentinel office is both identical and unique.
  • Identical because of our commitment to quality management processes that are ISO 9001:2015 Certified. Following this global standard ensures that customers will receive consistent service quality no matter where they do business with us.
  • Unique because the products, services, and programs that are delivered at each location are customized to meet the needs of the local population. Some offices only offer GPS, others installation and retrieval services, while some operate full-service Day Reporting Centers. Whatever the requirement, Sentinel customizes the offering to meet the needs of our customer.

The Riverside County office opened its doors this January in the heart of downtown Riverside, California. From this location, we serve the courts, adult probation, and the Sheriff’s Department with alcohol monitoring, GPS, RF and case management services.  The staff makes weekly visits to local county probation offices to help with any front-line issues.

In April, Fairfield, Ohio office went live! As is often the case at our customer’s request, we are co-located with our customer at the county jail. Supporting Municipal Court, Juvenile Probation and the Court of Common Pleas the Sentinel team delivers GPS tracking, installation and removal and alcohol monitoring services.

Monday, May 6, 2019 marked the grand opening of the Meriden, Connecticut office. Working with several departments in the judicial branch of the state, the office provides dispatch, inventory control services and coordinates the field service team.

Sentinel has had a business relationship with the state of Connecticut for more than 20 years. Investing in a local office allows us to build on that solid foundation. Meriden was the perfect fit, as it is centrally located with easy access to the entire state and has a good business environment.

The Sentinel team welcomed staff from several groups within the judicial branch.  At the ribbon cutting commemorating the occasion, the program director expressed his appreciation for the long-standing relationship with Sentinel and the new investment in a Connecticut office. He stated that this will help Sentinel to better understand nuances associated with traffic and locations that are likely to experience more crime.


Many thanks to all who attended this special event. Below are a few candid snapshots of the reception.

Sentinel Celebrates Second Chance Month 2019

By | Blog, Day Reporting Center, Reentry, Uncategorized | No Comments

The US SenateHouse of Representatives, and the White House have all officially proclaimed April 2019 as Second Chance Month in the US.  From the White House proclamation:

“…(we call on) all Americans to commemorate this month with events and activities that raise public awareness about preventing crime and providing those who have completed their sentences an opportunity for an honest second chance.”

Partnering with the National Reentry Resource Center * and other like-minded national organizations, Sentinel Offender Services is helping to bring awareness to the importance of successful offender reentry. Second Chance Month is a time when organizations and individuals focus on the importance of helping convicted criminals to successfully reenter society. This was first observed in the United States in 2017.


The world of offender management has changed since we began this business over 25 years ago. Sentinel Offender Services has changed and evolved as well.  We continue to help court systems, law enforcement, and corrections agencies to serve and protect local communities and help offenders get on the path to a better life.


Many of our most effective programs and tools are delivered every day through local offices, Day Reporting Centers (DRC) and Community Based programs across the US.

Throughout the month of April we look forward to celebrating Second Chance Month. We will share personal successes and new tools and technologies that help offenders stay on a path to a better life.


Research on Offender Programs and Promising Practices

By | Blog, Day Reporting Center, Reentry, Uncategorized | No Comments

In case you missed it,  the story linked below includes excellent data on the importance of investing in community-based programs for offenders.

In remarks from June 2018, NIJ Director David B. Muhlhausen emphasizes both the importance of Randomized Controlled Trials (RCT) and continuing to improve results. He references several studies from the past 10 years or so.

Here is the link to the article.

Three useful takeaways:

  1. Reentry programs that reduce recidivism are more important than ever.  The federal government has invested more than $1 billion in these over the past ten years and has committed another billion over the next ten years.
  2. Program content and delivery should continually improve.  Early programs that support this initiative show some positive results, but not enough.
  3. Programs must track and report results as objectively and scientifically as possible.  This takes time but is essential to have the greatest long-term positive impact on the professional community.

Read about a current Randomized Control Trial for a Day Reporting Center program designed to reduce recidivism in this research brief completed by the University of Nevada, Las Vegas, in February 2019.
