Gateway Security Service has deep roots in the St. Louis security industry and traces its history to Stoehner Security Service, one of the area's established names in private security. Founded by Terrence Stoehner, a former Chief of Police, and Christopher Smith, a longtime security professional and member of the Stoehner Security management team, the business built a reputation for dependable, locally managed security services throughout the St. Louis region and beyond.
In 2026, Gateway Security Service entered its next chapter under the Stoehner family's leadership, with Leslie Stoehner assuming ownership alongside her husband, Tim Stoehner, and his brother, Matt Stoehner. Today, Gateway combines that longstanding local history with experienced leadership, modern security technology, professional standards, and a continued commitment to dependable client service.
Trusted. Local. Committed.
