He is a full time personal trainer with over twenty years of experience and more than 70,000 training hours in homes, gyms and his own private training studio. Donnie is currently the co-owner of Fit Stop 24 Fitness Centers located in both Olympia and Yelm, Washington. Though Fit to Kill is his first novel, he is no stranger to writing, having written numerous articles on nutrition, weight training and fitness; appearing in newspapers, magazines and the Internet. In Fit to Kill, his experience as a trainer allowed him to truly immerse the reader into the world of fitness in this detective thriller. Donnie also has 13 years of military service in both the US Marines and US Army, serving as a platoon sergeant and acting first sergeant. His experience as a trainer and veteran was extremely helpful in writing Fit to Kill.
