TMac joined the Crossfit community in 2010 as an athlete and competitor at a local gym. After a short amount of time she knew that being a part of the health and fitness industry was her true calling. TMac began coaching Crossfit in 2012 and went back to school to receive her Bachelor’s degree in Health and Fitness Science. TMac graduated from the program in 2014 with honors and has been extremely successful in her new career field. 

In 2015 TMac headed to Portland Oregon for a position as the head strength and conditioning coach for a local studio. In 2016, TMac returned to her roots and returned to Madison to take a role as the Manager and Head Coach at the Crossfit gym she started at.  TMac remained in that role until 2019 when she was offered the role as Fitness Instructor for Madison College for the Wisconsin State Police Academy. Missing the Crossfit community, TMac has resumed her role as a coach and the General Manager for the Big Dane Collective community, and is so proud to call this her home.

During this journey TMac not only focused on a career change but also her own personal growth and continues to be an accomplished athlete. These accomplishments include 2012 Mid American Open gold medalist in Olympic weightlifting in the 69kg weight class, 2013 Pan American Master Olympic Weightlifting silver medalist, Wisconsin Olympic Weightlifting state champion and state record holder in 2012, 2016 and 2017 in the 69kg weight class.  2017 American Open Master’s Silver medalist in the 69kg weight class. TMac has a deep passion for Olympic Weightlifting, but stepped away to pursue other avenues of sports and fitness and is currently enjoying challenge rides for cycling and mountain biking.


What you love about coaching/working at Big Dane:

Being a part of a community where everyone builds one another up.  It’s amazing to see everyone celebrate each other’s successes. The best part of my day is witnessing the smile on a person’s face when they achieve something new, no matter how big or small the success!
