True Testimonials
David Glenn Security L.L.C.
  Security With Freedom 
As a current customer of David Glenn Security, I give this company my highest recommendation.  The quality of the work is superb and the service is extremely prompt.  Dave Glenn was able to get my system working when several other companies could not.  Since Dave took over managing the system and monitoring the alarm, I have had no further problems.  The cost was very reasonable for the amount of work done and, most importantly, it was excellent work.

Satisfied customer
So here's what happened - I became tired of being overbilled and underserviced by my alarm company, so I decided to make a change to David Glenn Security and it was one of the best business decisions that I have made.  I have not had a problem since I  switched.  I have actually expanded my system to include cameras and it was as if the technicians were invisible when they did the work. There was no disruption in my business and everything works as promised. I would recommend David Glenn Security for all your security needs.
