3-Gun Shooter

Dianna has a Bachelor of Science in Criminal Justice/Psychology from the University of Central Missouri and recently retired from the Tulsa Police Department after 22 years of service. Her assignments included patrol, street crimes, narcotics and gangs. She began shooting competitively in high school and found 3-Gun in 2009. By 2011, she’d sold her farm and all of her barrel-racing horses to focus on 3-Gun competition and supporting the 2nd Amendment.

Dianna has been highlighted by the NRA in “American Warrior”, and has also appeared The Washington Post and NRA Women. She is a co-host on “Shooting Gallery” and a cast member on "The Big Gun."

Dianna is passionate about introducing new gun owners to shooting sports and promoting the 2nd Amendment in a positive light.
