TESTIMONIALS
Brock Rutherford
Sentry Security does a fantastic job with communicating issues encountered on the project, intercepting would-be-thieves, and documenting their nightly patrols thoroughly. We highly recommend using Sentry Security for your construction project security needs.
Todd Craig
Working with Sentry Security has been easy and professional. They were receptive and timely with there response to my need for overnight security and set things up quickly. After confirming they could provide the services I needed I was contacted by the Field Supervisor to personally review our security needs and he provided contact info and personal training to the staff member that worked our property. I am pleased with the service and quality of staff provided. I have a second need at my location and contacted Sentry right away to set it up.
