Let me tell you about a positive experience I had had recently as your Service Manager, Donny, was finishing up with upgrading my Sentinal Alarm System. As we began to settle my bill, I began to cry uncontrollably. Donny was very supportive of my personal crisis and offered to keep me in his prayers. Later that day, I began to feel better. Donny thinks outside the box, which, in my opinion, is the best kind of employee for a company to have. Thank you Donny, for your healing prayers and for thinking outside the box.
