OUR COACHES

Donald Keller

Donald Keller

Owner/Head CrossFit Coach

Originally from Bonita Springs and second generation entrepreneur, growing up I always knew I’d work for myself. Prior to founding Ionic Fitness, my entrepreneurial journey began in middle school with the establishment of “Cuts R Us,” a lawn mowing enterprise. Later, during my college years, I pioneered an evening and late-night bus service catering to FGCU students.

Equipped with a dual degree in Business and Exercise Science from FGCU, I have since acquired numerous certifications in the fitness realm including Olympic weightlifting level 2 coach, nutrition level 2 coach, NSCA strength and conditioning coach and CrossFit level 3 coach. You will quickly learn that when you walk through our doors you will be treated like family, as Ionic Fitness is a part of me like my family is.
