The Fitness Coliseum Team
Hi Guys! I am Bri, Owner here at Fitness Coliseum. I absolutely LOVE what we do here. I love helping people find their confidence, improve their health and make themselves a priority. I am so honored to be a part of so many amazing people's lives through Fitness Coliseum.

A little about me...I was born and raised just down the road in Ovid-Elsie. I moved on to Michigan State University, GO GREEN, where I earned by bachelor's degree in Dietetics. I then headed to the sunshine state for my dietetic internship at the Bay Pines VA Healthcare Center. I  am a Level one CrossFit coach and have been coaching fitness and sports  for 10 years!

When I'm not at the gym you can find me spending time with my husband, family and friends.  Get ready for plenty of stories about whatever project I happen to be working on at the time!

I love to work towards my own fitness goals alongside our members! You can often find my husband and I competing in CrossFit competitions or races on the weekends! If there is anything you would like to know, feel free to ask! I am an open book and love to talk :)

Meet our team below! They are amazing and I couldn't have asked for a better group to work with!
Fitness. Community. Family.
