America's Oldest Home Study Gunsmith Program

The Sonoran Desert Institute traces its roots in firearms education to its beginnings in 1921 as the Scottsdale School of Gunsmithing, and since that time it has transformed into an internationally recognized school offering multiple programs, including an Associate of Science in Firearms Technology degree and one of the nation's best Gunsmithing Certificate programs.

Initially founded by a World War I field artillery officer, the school continued its military tradition under the ownership of a World War II B-17 navigator returning from the European theatre, and has since developed into an accredited college serving military veterans, active duty service members, and anyone else looking to advance their knowledge and career skills!
