Chief Instructor/CEO - William J. "Bill" Joyner


Retiring after 20 years in the United States Marine Corps serving in counternarcotics operations, the Pentagon during and after 9/11, and Operations Iraqi Freedom and Enduring Freedom our Chief Instructor decided to put his hard-earned skill sets to good use and, following the adage, “Do what you love and you’ll never work a day in your life”, founded Interritus, LLC.


As an avid proponent of the inalienable right to self-defense, an accredited Texas Department of Public Safety Firearms Instructor, and an NRA Instructor, William has developed his courses to give the everyday, law-abiding citizen a fighting chance to defend him- or herself whenever the situation arises and to provide a solid foundation on which Interritus Students can build as they move on to more advanced “tactical” training.

Instructor Certifications: DPS LTC Instructor, DPS School Safety (Counter Active Shooter) Instructor, Private Investigations Instructor, PSB Level II and III Security Officer Instructor (Classroom AND Firearm)

Personal Certs/Registrations: License-to-Carry, Level IV Personal Protection Officer, Private Investigator
