Welcome to Mahoney CrossFit, the leading CrossFit gym in Marion county. We offer a coaching and trainer staff that is second to none! Our staff is comprised of an ownership team, a head coach and coaching instructors, a small cadre of coaches, and an extensive coach apprenticeship program.

Our coaching staff draws from a large and diverse knowledge base, ranging from formal undergraduate education in exercise science to national and regional certifications, and advanced specialized certifications and workshops. We pride ourselves on our never-ending quest to seek out the latest cutting-edge information and research in health, longevity and performance. We dedicate ourselves on delivering this to our members and the community in a progressive and professional manner.

To be a member of our staff and coaching cadre, experience is a must. Our staff has to prove their place among us by undergoing a 2+ year accredited apprenticeship through the MadLab Group Professional Coaching Development Program. This program involves training in our system and methodologies, education in human movement and exercise sciences, effective coaching skills and techniques, supervised hands-on coaching experience, and our testing procedures. Once completed, our coaches must obtain recognized accredited training certifications and be willing to continue to grow and pursue more specialized, advanced education.

That's the Mahoney CrossFit coaching difference!
