The cadre at TDSA Tulsa consists of Municipal, State and Federal Law Enforcement personnel. We are competition shooters and have had the privilege of training some of the finest people in the country.

Our students have consisted of people from the US Secret Service, FBI, DEA, Force Recon Marines, US Army, Naval Special Warfare Center, Air Force SERE Instructors, Security Forces Outfits, Oklahoma Highway Patrol, numerous different law enforcement agencies, professional competitive shooters, IDPA and USPSA competitors and firearms instructors from several different agencies.

We have proven ourselves on the range and in the classroom and challenge any organization to match what we do for our students. No other cadre in the country will treat you with the respect that we do. No one can compete with the level of performance we see in our students. When you stop learning, you deny yourself the opportunity to grow. If you think youíre good enough, you arenít! Check your ego at the door and come train with us. You wonít be sorry!

Eric Fuson

IDPA Distinguished Master

In the last 15 years IDPA has watched the talent and skill level involved in the shooting sports steadily increase. Because of this continued trend and at the request of the membership IDPA has decided to add a new classification above our existing Master class. This new classification will be known as Distinguished Master.

The new Distinguished Master class will highlight those members that have made a great personal commitment to reaching the very highest levels of skill and proficiency with a handgun. To reach this level a competitor must have spent considerable time and effort at refining their abilities. As such, the requirements for being inducted into this classification will be very stringent. The initial inductees to the Distinguished Master class have already proven themselves by their placement at one of the two IDPA National Championship events in the last five years. These members have placed as Division Champion or been within 3 percent of the Division Champions final time. One of the inductees TDSA's own:
