A Veteran Owned Business - A family tradition of Military Service.

Military Service is the tradition of John J. Chmelir and his sons.  He was a WWII B-24 flight engineer and gunner in the 15th Air Force and flew 38 combat missions out of Panatella, Italy.  After the war he was commissioned a Second Lieutenant of Infantry in the Army National Guard, eventually transferring to and retiring from the Air National Guard as a Major after 24 years service.

John Chmelir's sons, John D. and Peter never considered not serving.  John D., Company Owner, served 11 years on active duty as an Army Engineer and another 18 years in the Army Reserve retiring as a Lieutenant Colonel.  Peter, a Naval Aviator, flew for 9 years on active duty and retired as a Captain after 28 years active and reserve service.


John D.'s sons John M. and Bill flew together in the Colorado Army National Guard.  John retired after 17 years as a Staff Sergeant and UH-60 Blackhawk Crew Chief from the Alaska and Oregon Army National Guard.  Bill retired from the Oregon Army National Guard after 22 years as a Chief Warrant Officer 3 Pilot flying OH-58 Kiowa Scout Helicopters.



Together that totals over 120 years of Chmelir service.  Between 1941 and 2014 there have only been 6 years without a Chmelir in uniform and some years as many as four serving at once.
