Hey, I’m Coach Kate and I am a rising college freshman at the University of Georgia! I’ve been swimming at ECHO since I was three years old and this is my fourth year returning as a coach. I was also apart of Lakesides varsity swim and dive team for four years. I love to teach all strokes, especially butterfly, but most importantly I value teaching athletes how to feel calm and comfortable in the water. Other than coaching, I love quality time with friends to build my connective skills. I also was apart of Lakesides varsity cheer team which helped me build social and leadership skills that I connect into my coaching!
