Megan Baryenbruch

Assistant Coach

My name is Megan Baryenbruch. I swam for 15 years on the Spring Green Dolphins, and 4 years on the RVHS girls swim team. This summer will be my 4th summer coaching, and I’m incredibly excited to be here another summer. My favorite thing about coaching is seeing how much the swimmers change and grow throughout the season, whether it be through their race times, work ethic in practice, enjoyment of the sport, or interactions with their teammates. When I’m not coaching this summer, you’ll still be able to find me at the pool teaching swim lessons or lifeguarding. Outside of swim team I recently graduated with a Bachelor of Science degree in Human Development and Family Studies from the University of Wisconsin- Madison. After the season I will be moving to the Twin Cities in Minnesota to work for College Possible as a college prep and admissions coach for underserved high school students.
