Kelley O'Sullivan, Fit Boss-Adventure Seeker


Kelley O'Sullivan



Since I've been working with Kelley, I've returned to running because my overall strength is improving. Confidence in my ability to try new things has grown: never thought I would stand up paddle board, paddle board yoga, kick boxing or finish obstacle course races, but I have. Nutrition education and awareness are added benefits. Besides fitness is fun and I'm not stopping anytime soon.


Client since 2015

Kelley has been my cheerleader, fitness and wellness confidante, challenger, and biggest believer in things I can do. She's gotten me to try and do kickboxing, TRX, stand up paddle board yoga, and so much more. I love our workouts and time together, and love the bond with the fellow “torturees” . Fitness is fun when Kelley is in charge.


Client since 2015

Kelley is an inspiring coach and leader. I have significantly improved in flexibility, strength and balance since I started working with her. She listens and cares about her clients and works with them to make things happen. She is the best in my experience.
