Smith Protective Services was founded in 1903 and is the largest privately-held security service company in Texas and the oldest in the U.S. Smith specializes in the needs of Texas companies, and unlike many of our competitors, the management team you work with today is the same team that you will work with tomorrow. Stability in our management team has, in part, been responsible for the consistency in our customer base-- we've worked for some of our customers for decades!
