Our Team

Kaisa Kerwin

Founder, Owner & Lead Trainer

Kaisa is certainly no newcomer to the world of fitness. Starting Tae Kwon Do at just 4 years old and earning her Black Belt by age 8, she’s been a ninja her whole life! She trained her heart out and competed in hundreds of tournaments, even making it all the way to the Junior Olympics. When she Finished high school, Kaisa became a fully licensed Multi-Engine, Instrument-Rated Commercial Pilot, but after flying for 6 years, she realized she wasn’t doing what she loved, which was teaching and helping people.

In 2009 Kaisa completely shifted gears and opened up Kaisa’s Kickboxing. For 5 strong years she poured her heart into Kaisa’s Kickboxing, watching it grow and grow. When it finally outgrew its location, there was only one obvious choice: go bigger. In 2014, The Fit Shop was born, turning Kaisa’s group of dedicated clients into a full-blown fitness community, and it wasn’t long before people started to take notice (read more).

Creating a judgment-free, kind and inspiring space where people can go not only to get in the best shape of their life, but to see familiar faces and feel just as important as the person next to them is Kaisa’s favorite part about being in this business. The energy you feel when you’re at The Fit Shop is Kaisa’s heart and soul. If you haven’t felt it, then you haven’t been here, so come to The Fit Shop and check her out!
