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
