Terri Servais


Terri Servais comes from an extensive background in fitness. Her career started as a group exercise instructor while attending college as a part time job. After college she continued to teach part-time, and found this to be her true enjoyment. After attaining her Business Degree from UW-Parkside, she went out into the corporate world and hated it. It became a struggle to get through an 8 hour corporate day, while still loving what she did part-time. Terri then decided to get certified as a Personal Trainer through ACE and AFAA and continued to get different certifications for Pilates, Group Exercise, Spinning and Pump.

Brandon Lueck

CrossFit/Barbell Coach

Hi my name is Brandon Lueck. I was born in West Allis, WI in 1987 and moved to Muskego in 1995. I grew up playing a little bit of everything to burn off all that extra energy most of seem to have as kids. Early on I was active in tee-ball, gymnastics, and tae kwondo. In middle school I started to really get into football and basketball. I feel like playing a different sport every season helped my overall athleticism and definitely made the transition to CrossFit an easier one for me than most.
