Jedediah Stone Associate NAFI MCFIJedediah Stone, Associate MCFI 3/2021-3/2023:

Stone was raised in North Pole, Alaska. It was there, working as a wildland firefighter where he says he discovered the joys and possibilities of aviation, specifically involved with flying helicopters. He then spent the next several years working in the summers to save up so he could fly in the winters and inch closer to his goals.

In the summer of 2018 Stone received his CFII rating and started his career as a flight instructor north of New Mexico and slightly south of Wyoming. He has thus far spent a year and a half teaching the newest crop of helicopter pilots the finer points of aviation, safety, and professionalism.

Stone says he enjoys helping the next generation learn to be safe, knowledgeable, and competent pilots because we all know we will someday somewhere share the airspace with them. He hopes that everyone achieves their dreams of flying because all of us understand just how amazing it really is. He adds that he is committed to continuing his learning and growth as a pilot, instructor, mentor, and person so that he may help as many of them as possible.
