Our History

STT Corporate Headquarters – Mt. Pleasant, MI

STT was founded in 1973 by Dave Rusch, former Police Officer in Lansing, MI. Dave left the public sector to fill what he felt was a lack of available quality services  in the areas of: security, investigative, and business loss-prevention services.

In its infancy, STT’s core was comprised of private investigative and retail loss-prevention services. Due to strong reputation of integrity and professionalism STT”s service offerings quickly expanded to include security personnel for hospitals, shopping malls and several industrial locations.

Since that time STT has grown into a national organization with multiple divisions catering to various types of clients throughout the United States.  Despite major growth the company has always held on to the ideals and goals set forth from day one -build and maintain mutually beneficial business relationships. Each and every service offered by STT is personal and handled with professionalism.

Dave Rusch retired in April of 2017. At that time, 3 key employees purchased the business from Mr. Rusch, all of which have been heavily involved in the businesses successes over the last 10 years.
