Greg Mack

ACE-CMES, ACE-CPT
Founder and CEO, Exercise Professional Education, LLC ​and Physicians Fitness, LLC; Columbus, OH

As Founder and CEO, Greg’s vision for Physicians Fitness was shaped over 29 years ago, while he was working as a lay assistant to physicians in a sports medicine clinic. It was during this tenure that he became award of an  unfortunate reality: Most of the patients of the clinic were there as a result of poor physical conditioning. He observed that the patient base consisted of individuals who would return to the clinic for treatment of re-injury to a problem area, or the development of new symptoms, possibly due to compensation patterns created by the original pathophysiology. The medical and chiropractic staff encouraged these patients to participate in exercise and fitness programs, but had neither the time nor the resources to effectively assess, develop, and implement a safe, global health-fitness plan.

Greg’s Education & Formal Training

As a graduate of the Navy’s Nuclear Engineering School, Greg used his foundation of engineering skills, his enthusiasm for fitness, his academic certifications – ACE–Medical Exercise Specialist (CMES), ACE-Personal Trainer (CPT), (American Council on Exercise) and Resistance Training Specialist Mastery (resistancetrainingspecialist.com) – and his extensive experiences working with a wide variety of medical professionals to develop the Muscle System Specialist™ Certification Program and the Mobility Profiling Method of pre-exercise physical assessment.

Experience to Lead, Awareness to Guide

Greg’s experience in working in such diverse venues as community gyms, chiropractic facilities, and medical practices enhanced his awareness of the wide gulf that exists between the medical community and fitness facilities, particularly for those individuals trying to recover from, and manage, diagnosed diseases. This led to the development of a comprehensive documentation and communication system that coordinates exercise and fitness programs for individuals with diagnosed diseases from the medical community, the core of Physicians Fitness operations.

Publications & Memberships

Greg’s involvement in the fitness industry includes authoring articles for fitness and medical publications, presenting relevant topics to fitness professionals at continuing education conferences, and achieving the “Master Level” designation as a personal fitness professional from IDEA. Greg received the IDEA International Personal Trainer of the Year Award for the year 2003 and was the Chairman of the IDEA Personal Trainer Committee, an influential body steering important issues related to fitness professionals.

Brandon O’Connor

CMSS, RTSm​
Founder, Austin Muscle Restoration; Austin, TX

For the last 18 years, Brandon has been helping people live a better life through resistance-based exercise and Muscle Restoration. His passion for exercise started at age 15, when he began lifting weights for sports. That passion grew to the point that he wanted to help others reap all of the benefits he found through regular strength training.

As Brandon’s personal training practice grew over the years, he discovered his niche: helping those who were suffering the effects of traumatic injuries, surgeries, and disease states. This led him to found Austin Muscle Restoration in 2009 and the Autoimmune and Injury Gym in 2015. This is where he and his team put their knowledge of Anatomy, Physiology, and Biomechanics to work on a daily basis. As a course facilitator for the Muscle System Specialist program, he hopes to help others in the exercise and wellness fields learn new concepts of neuro-muscular sensation, communication, and control, to better serve their clients.

Past certifications: Master Level Muscle Activation Techniques, ISSA CPT, NASM CPT, NASM PES, Cooper Institute CPT.
