NATE
Nate Mentzer is our newest Manager On Duty with a deep resume in the fitness field. Nate is both a Certified Personal Trainer and a Corrective Exercise Specialist both certifications with NASM. Nate says he is in the fitness business because “the body is an amazing piece of machinery.”
Nate took his certifications to the next level obtaining the Corrective Exercise Specialist certification. That certification allows him to work with clients on injury rehabilitation as well as correcting muscle imbalances. It typically incorporates myofascial release and is a slow and steady focused training methodology that builds strength to injured and surrounding areas while protecting against re-injury.

Nate describes himself as “a goofy guy” who loves making people laugh and who embraces his kooky side!
