Sentinel Offender Services – Why Work For Us?


About Sentinel Offender Services

Since 1993, Sentinel Offender Services has been a trusted partner of courts, sheriff departments, probation and parole departments, and other law enforcement agencies from across the country. We provide comprehensive case management and offender-management services.

Sentinel pioneered the first participant-funded program model in which all program fees are paid for by the participants directly, saving taxpayers millions of dollars in jail costs. At the time of enrollment into a participant-funded program, Sentinel staff conducts detailed financial assessment on the individual. The results of that assessment are used to establish a suitable daily fee for the participant—based on their ability to pay—that is accordance with the supervising agency’s approved sliding fee schedule. This no-cost approach for the government can be provided for any of the services we offer.

Through these programs, Sentinel has been able to dramatically reduce the cost of expensive supervision for municipalities and their law enforcement agencies—all while operating with strict adherence to the rules, guidelines and oversight of our customers.

Moreover, our success has been built upon our ability to provide superior value through comprehensive, customizable and scalable services that include hardware, software, local community-based personnel and best-in-class 24/7/365 offender monitoring capabilities.

Robert Contestabile

Founder + Chief Executive Officer

Robert Contestabile has more than 30 years experience in the security and monitoring industry. While serving as President of Florida-based Wackenhut Monitoring Services, Mr. Contestabile purchased the company and Sentinel Offender Services was born in 1993. In the intervening years, Mr. Contestabile has grown Sentinel into one of the largest and most successful electronic monitoring companies in the industry with over 225 customers in 48 states.

In that time, Mr. Contestabile has created an extremely successful track record and has become an undisputed leader in a tumultuous and challenging industry. From the very beginning Mr. Contestabile and his team at Sentinel began building a legacy of innovation—starting with the creation of the first offender-funded monitoring program in the nation. In 1993, Sentinel created the inaugural offender-funded monitoring program that required the participant to pay for all of the fees associated with participating in the program—this truly unique model was the first of its kind. Since its inception, Mr. Contestabile has successfully implemented programs like this across the nation, allowing agencies to operate highly-effective and cost-efficient electronic monitoring programs at no cost to the agency or tax payer.

A key to the successes of these programs has been Sentinel’s 24/7/365 National Monitoring Center, a state-of-the-art electronic monitoring facility located in Irvine, California. Mr. Contestabile created this multi-platform hub to offer national and international customers alike numerous agency- and offender-funded monitoring options that include RF, GPS, alcohol and domestic violence monitoring and prevention. A native of Pennsylvania, Mr. Contestabile earned his Electrical Engineering Degree from the University of Pittsburgh. Since relocating, he enjoys spending the mild winters and beautiful summers that southern California has to offer with his wife Gwen and their wonderful grandchildren. An avid golfer, Mr. Contestabile can often be found taking advantage of any number of California’s fine golf courses.

Darryl Martin

As Chief Operating Officer, Mr. Martin maintains executive responsibility for the company’s internal, technical and field operations, which includes the company’s network of field offices that specialize in case and offender management programs that are designed to aid program participants.

Mr. Martin is a graduate of Chapman University and received his MBA from the University of Redlands.

Mark Contestabile

Divisional President + Chief Business Development Officer

Employee Spotlight – April 2017

      Sentinel would like to highlight an individual who has shown the progression an employee can achieve at Sentinel Offender Services. We would like to spotlight Paula Guardado.

For over a decade, Paula has risen through the ranks from a Case Manager, to a Branch Manager to her current position. She is responsible for the day to day operations of all of Los Angeles County adult and juvenile programs including the oversight of Sentinel Staff. Los Angeles is a demanding program that requires diligent attention to detail and follow through. Once Paula provided oversight at our Los Angeles location, we have maintained glowing audit reviews from the department.

Paula has been utilized to onboard new employees, train agency personnel and launch new programs throughout the United States. She is always willing to step up and help the organization whenever needed at other, out of state locations. In a few words Paula is DEPENDABLE, PROFESSIONAL and RESPONSIBLE. Thank you Paula!

    Application

    I applied online. I interviewed at Sentinel Offender Services (Atlanta, GA) in July 2015.

    Interview

    It was a two to one ratio. It was very nerve wrecking but over all it was ok. After everything was said and done I asked questions about the company as well like -what was the turn over rate and how can I gain from working with the company.
