Mary started Crossfit in 2009 when she needed to build some strength for her running and triathlon training. As a former collegiate swimmer, Mary is well-versed in cardio and endurance training, but she wanted a little extra to get her up and over the trails of Mt Tam. While never a full-time or exclusive CrossFitter, Mary has enjoyed how complementary CrossFit has been to all of her athletic endeavors.

When not training, Mary can be found on the pool deck coaching water polo (both high school and with the Olympic Development Program) or in the classroom teaching English.

Greatest CF accomplishment: completing “Mary” Rx the day before she turned 40.
