A&P
I moved to Sherwood, Oregon in 1972 at age five from long beach California. I got my first taste of general aviation at Twin Oaks at the age of 10 when family friends flew up in their Cherokee and I remember thinking what a cool job it would be to work here. I spent 4 1/2 years in the Coast Guard and then went to OIT where I got my bachelor degree in manufacturing engineering technology. After that I returned to the Coast Guard and served 23 years during which time I got my private pilot license and instrument rating. In 2017 I once again pursued my passion for flying and enrolled in Central Oregon Community College professional pilot program where I completed my commercial, CFI, CFII, and multi engine ratings. In 2018 I became a full time flight instructor and also worked for Leading Edge line department on the side. I instructed for leading edge and COCC for 4 years. In 2022 we moved back to the valley when my step-daughter had her first child and now I am a grandparent. I got a job at Hillsboro Aviation as line tech, then avionics tech, then line manager. While at Hillsboro, friends said I should use my Coast Guard experience and become an A&P, which I had actually started the process for back in 2003. I was offered the job at Twin Oaks to pursue my apprenticeship, and am actively working toward finishing my A&P. I feel very privileged to be employed at Twin Oaks and can’t think of a better family to work for.
