Mayumi learned to swim before she could walk, according to her father who is also a swimming coach. By age 8 she was swimming competitively, competing in both the pool and in open water aquathlons. However, before she even started swimming competitively, she was the coach’s mini-me with a stopwatch and a clipboard.
Aside from swimming, Mayumi enjoys various sports including ball hockey and was the captain of her high school ball hockey team. While both swimming and ball hockey are tough sports, swimming can be a very lonely one. Mayumi understands from firsthand experience that sometimes it’s hard to grind through those early morning swim practices without the support of family, friends, teammates, and coaches, which is why Mayumi wants to be the coach who motivates swimmers to keep swimming. She is looking forward to working with all the coaches, swimmers, and parents at RHAC to all swimmers achieve their goals.
