Tony Schumacher

I began my swim journey in high school, going out for my high school swim team freshman year. Right after the season I joined the local club team; Loveland Swim Club. I had a very inspirational coach that summer that graduated me up to the next group that fall. The coach of that next group I was places in shaped my life. He had one on one conversation with me that led me to the path I am on today. I'm here to pass on that inspiration and one on one attention to every swimmer I can.

 I swam year round in high school with my club team and high school team. I made a lot of progress during that span. I came through with all conference honors, top 10 state finishes, and 2 school records. The coaches I had through the process made me realize my potential and fulfill it by showing up and putting in the effort it would take. I am grateful for my experience and will create a positive experience for all the swimmers I come across.
