Tim Jenkins

Head Age Group Coach


Coach "J" has been a member of the B.R. Ryall YMCA Swim Team coaching staff for five years.

A lifelong swimmer, Tim started his competitive swimming career as a child with a Boys & Girls Club. Tim was a five-time Prep School All-American at Deerfield Academy, and went on to swim for Bucknell University. Today he competes as a Masters swimmer and is a three-time National Champion in his age group.

Tim carries the values that he learned as a young swimmer with him today, and feels lucky to have an opportunity now to share those values with young swimmers to help them be the best athletes and individuals that they can be.

Dave has been an integral member of the B.R. Ryall YMCA Swim Team coaching staff for more than 15 years. A love of swimming is shared by the entire Sivak family.
