Lieutenant Alan D. SawyerLake Dallas Police Department
I wanted to take the time to tell you how much I appreciate Defender. This is our 4th year using Defender to outfit our police department’s police vehicles. During this time I have worked closely with George Sever and he has been absolutely outstanding, always going above and beyond, working with me on configuring the vehicles and getting them ready to go to the technicians.

I am taking the time to write you this email about the job your technician did on retro fitting these Tahoes for us. I normally do not write these kind of emails unless I am very impressed by the work done and professionalism shown. So let me first state that your technician I feel has gone above and beyond on the work he has done for us. I never once had a problem with getting ahold of him. He kept me up to date on his work progress every step of the way. I just wanted to personally thank you for assigning him to do this work.

I wanted to take a moment to send some praise for (whomever) assembled our latest canine vehicle. I have been in law enforcement for 28 years, ten of which as a canine handler. I have installed, helped install, or operated many vehicles equipped with a canine insert. The vehicle we received from Defender Supply is the first vehicle I have ever experienced that was absolutely rattle free! I know this may not be an important issue for some, but believe me when I express that this is a HUGE deal for a canine handler. I am not sure what sort of witchcraft your tech used to eliminate all the rattles, but whatever magic he invoked, it sure made a difference. LOL. As always, we are extremely pleased with your work product. Your staff (even George Severe) have remained extremely helpful as usual. (I enjoy messing with George, he has a great personality!) We are looking forward to receiving the remainder of our vehicles and continuing our business with Defender Supply in the future!Marc A Fletcher,
