Donny and the technician were super. My system is older and they took extra steps to find info on the system and reset it. Gave me perfect instructions and the system is working great. I have been a customer for over 20 years and remain a very satisfied customer. Linda Tunnell

Our company recently retained the services of Sentinel to provide security and monitoring for our Dallas warehouse. Donny on the Sentinel team was our Technician and systems expert and provided exceptional service and subject matter expertise. Donny's work and Sentinel's dispatch service couldn't have come at a better time as shortly after our system installation we had an attempted break in. Our alarm system and notifications from Sentinel's best in class dispatch center prevented our business from having any losses and kept our inventory safe. I'm very pleased with Donny and the entire Sentinel team!
