Founded by Frank Yurkovich in 1992 after an 18-year career with the U.S. Navy Special Warfare (SEAL) Community and Naval Special Warfare Training Center (BUD/S) with a single goal: to provide the most comprehensive, up-to-date, and professional protective security and training services in the business today.


Whether online, in the classroom, or on the range, we continue to strive for new and innovative ways of providing our students with cost-effective and forward-thinking training solutions. 

In 2006, Frank Yurkovich, along with a dedicated group of administrative and security professionals, set forth to expand GSE’s operational capabilities with the establishment of a permanent training facility in Winchester, Virginia.


Supporting our local community is at the core of who we are. Sponsoring local charities and various youth programs are just some of the ways we give back.

Situated on 7.5 acres in the Shenandoah Valley, GSE’s sprawling facility includes four training rooms, administrative and staff offices, a student break room, warehouse, and 25-yard semi-enclosed flat range. 


You can count on our timely response to your questions both before and after enrollment. Over 90% of our students return to GSE for their training needs.
