Gregg began flying as a personal interest in 1978. He progressed through his private, instrument, commercial, multi-engine and CFI ratings, and was encouraged by a friend to pursue a job as a corporate pilot. He has been teaching since the mid-nineties, and has been flying as a corporate pilot for 24 years. Gregg has type-ratings for four different jet aircraft, and has around 18,000 hours of flight time. As an instructor, Gregg particularly likes to help students understand risks, and learn habits and procedures to enjoy flying safely.
