I swam on the CCC swim team for 11 years and I’ve been a coach for the marlins for 7 years. My favorite stroke has always been backstroke, but I love teaching the basics for all four strokes in swimming. I started as a CIT with the mini marlins in 8th grade and I’ve been working mainly with the 8&unders since. I am attending the University of Portland, studying to be an elementary school teacher. I am excited to be back this summer for another great season!
