Hi Stingrays! I’m Coach Kathryn, and I am back as your head coach for the 2026 summer. This will be my last summer as your head swim coach, and I'm hoping to make this one of the best! I returned to coaching in 2023 after a few years away and I am excited to work with both our familiar and new swim team faces. I previously coached the Stonebridge Swim Team starting in the summer of 2010 up until the summer of 2019. Before that, I coached at my parent’s neighborhood, Summerfield North, for many years, starting at the age of 15 as a 6 and under coach. In addition to coaching summer swim team, I have previously coached year-round swimming with WAVE and have helped coach high school swimming, soccer, and rowing. I was also a school teacher for 13 years, but left education to start my own personal training business here in Stonebridge! I am not only your swim team coach, but also the swim team coordinator and your neighbor! My children, Spencer and Holden, participate on the swim team so it truly is a family affair. I believe that summer swim team should create a love of swimming and bring neighbors together. I aim for our swimmers to have a strong foundation in all areas of their swimming. I believe that good technique builds speed. I am looking forward to this summer and having you be a part of our team!
