Coach Seth Donnelly - Head Coach email at:

Seth Donnelly has been coaching competitive swimming for over ten years. His coaching journey began in Anchorage, Alaska, and he has learned much from experience working with teams in Virginia, and Indiana (his home area).  His love for the water and the smell of chlorine began at age eleven and has not stopped. Three years of hard work helped him become a four year letter earner at Penn High School, a four year sectional finalist, and part of a high school state runner-up team his senior year.  He’s had the privilege and pleasure of teaching swimming at all ages and levels, from toddlers through high school state finalists and even masters nationals qualifiers.

“The destination is never worth it if you can't appreciate the journey to get there.” -Coach Seth


Coach Bryan J. Morrison, Ph.D. - Head Age Group Coach email at:

Bryan has been coaching for 20+ years at all levels of swimming, from leading a SwimAmerica ( program to being a Division I head coach. He earned his doctorate in exercise science studying the biomechanics and physiology of swimming at Arizona State. While attending ASU, he coached 8 & under girls for Sun Devil Aquatics. His swimmers were referred to as ducklings because they followed him around single file on any pool deck. Locally, he has coached with the Warsaw YMCA and Concord swim teams. As a coach for Masters swimmers, he helped an athlete drop over an hour in an ironman.  As a certified strength and conditioning specialist (CSCS -, he worked with an eighth grade volleyball player, who managed to accidentally win a 5K.  His coaching philosophy is to educate, lead by example, and instill a love of swimming and exercise in people of any age.
