The mission of Tri-State 1 is to provide the most highly trained and qualified personnel in the DMV area (Washington DC, Maryland and Virginia).

In addition, we utilize the world's most advanced technologies and logistical processes from our administration to our operations.


Our #TrainingFacility (open to the public) is certified in Washington DC, Maryland and Virginia. It is owned, managed and operated by local and state law enforcement professionals. With over 100 years of combined law enforcement experience and expertise coupled with innovative and interactive courses of study, Tri-State 1 is the #1 training facility on the East Coast.

The Tri-State 1 family of companies are #minority owned and based in Prince George’s County, Maryland, within a few miles of the Nation's Capitol.
