Hello! My name is Jami DeHaan and I’ve been a certified Zumba instructor for 11 years. I started dancing at age 4, was a member of the East Kentwood varsity dance team and I filled in as the JV dance coach after graduating. I’ve always enjoyed dancing and coming up with my own choreography. I became a Zumba instructor to share my love of dance, while encouraging students to just be themselves and have FUN!

Brian Harris
Strength & Conditioning Coach

Hey Max Effort Family, I am coach Brian. I grew up on the east side of the state in Fenton, Michigan.  Playing soccer at a high level and other sports was my life.  I have always been fascinated with sport performance and continue to learn and grow in the field as much as I can.  After high school I attended Central Michigan University, completing my Bachelors Degree in Exercise Science.  Soon after I had the opportunity to move to South Florida to train athletes of all ages.  After several years working with high school, collegiate, NFL combine prep and professional athletes, I earned an opportunity to be the Head Strength and Conditioning coach at American Top Team in Coconut Creek, Florida.  While there I was one of many puzzle pieces to help bring American Top Team their first UFC champion, Robbie Lawler.  A couple notable athletes I have had the pleasure of working with include Robbie Lawler, Dustin Poirier, Jorge Masvidal, James White, and Jeff Conine. I am excited to bring professional standards to anyone looking to improve their overall athletic performance and fitness levels.
