I'm a life-long swimmer who has experienced many aspects of the sport! I was fortunate to find my love for the sport as a 4-year-old in a learn to swim program and still enjoy doing laps in the pool today! I've altered my training and biomechanics throughout the years for my own success, as well as the success of the swimmers I work with! I love the sport of swimming, and I invite you to join my love for the sport!
