About the Founder Haggan Aviation was founded in 1996 by Eugene “Geno” Haggan. With over 38,000 square feet of heated hangar space, Haggan Aviation is the largest full service repair facility in the Southwest specializing in small to mid-size corporate jet maintenance. A licensed aircraft mechanic, Geno built his company based on the simple principles of honesty, communication, quality workmanship, and safety. Principles he firmly believes should be standard industry practices in all repair facilities. Driven by this ideology, Haggan Aviation sets the bar higher, continually challenging its employees, technicians, and customers to expect nothing short of the best.
