Sentinel Receives Third ISO 9001:2015 Certification in Less Than 18 Months

Sentinel Offender Services LLC announced today it has successfully completed its International Organization for Standardization (ISO) 9001:2015 Recertification Audit. Sentinel expanded the scope of its quality management program to include certification of its field operations. Field operations consist of branch offices across the U.S. from which the company delivers community-based offender management programs and services. The addition of the company’s remote field offices to its ISO scope is an expansion to an already robust set of ISO certifications.

Sentinel ISO 9001:2015 Certified

The successful completion of this recertification audit is confirmation that Sentinel maintains policies, procedures, and processes that are designed to meet customer and compliance requirements. According to ISO, the 9001:2015 certifications are designed to help organizations achieve sustained success through the implementation of effective quality management systems. ISO certification provides customers greater confidence in the certified organization’s ability to consistently provide products and services that conform to requirements.

To achieve ISO 9001:2015 Certification, Sentinel documented the policies and procedures necessary to support the production and delivery of electronic monitoring technologies, monitoring center services, and community-based offender management programs. The certification process included the review and observance of each documented process by an independent auditor.

”Continuous improvement of our products and services is a strategic initiative for Sentinel to which we are committed,” said Darryl Martin, Sentinel’s Chief Operating Officer. “Our field operations team is the face of Sentinel to our customers. This expanded scope and recertification means that every customer throughout our portfolio is assured of receiving consistent and reliable services and products. Further, it provides objective validation of our commitment to continuously improve our products and services.”

Sentinel’s Chief Business Development Officer, Mark Contestabile, added, “The expansion of ISO 9001:2015 scope to include our field and branch operations supports another of our strategic initiatives: to grow our locally delivered programs and services.  Operational excellence creates customer service excellence and this creates extremely satisfied customers. Satisfied customers fuel company growth.”
