Smith Thompson Security

"Company Born Out of Tragedy"

Occasionally when talking to a prospective customer, I hear the words "You have no idea how I feel" when they tell me about their horrible home burglary experience. Unfortunately, I have to respond that I know exactly how they feel since my own family suffered a devastating burglary violation many years ago. In fact, the very day we buried my dad after he was killed by a drunk driver back in 1978, our house was completely ransacked and practically everything of value was taken.

I will never forget the depth of despair that my mother was plunged to when she saw the drawers, our belongings, the mess strewn throughout the house and even worse, the police fingerprint dust everywhere when we returned from the out-of-town funeral. Our family completely understands the misery that follows such an act. A burglary of your home is generally regarded as a violation, some even referring to it as a rape. Steve Blow of the Dallas Morning News wrote a column on the 25th anniversary of our burglary chronicling my mother's feelings about our burglary that was never solved by police.

I became fascinated with security system technology after this tragedy and along with my best friend Jim Smith and then-girlfriend Lynda, started Smith Thompson in 1978. We've come a long way, and are now the largest independent, full-service alarm company in Texas. We protect thousands of families and businesses in the Dallas/Ft. Worth metroplex, greater Houston area, and San Antonio as well as over 150 other cities and towns in Texas. Lynda, myself and our children, who are now very much involved in the business, are honored that you are considering us to protect your home. Our family is here to serve your family.

Warmest Regards,
Mark S. Thompson
