Richard Ulm, DC, MDT-Cert

Dr. Richard Ulm is a practicing chiropractic physician in Columbus, Ohio where he treats the full spectrum of patients from complex cases trying to avoid surgery to Olympic athletes.  A former national level track athlete and strength coach himself, he combines these experiences with his medical training to provide functional, patient-specific treatments for everyone who walks in his door.

For the last 15 years, Dr. Ulm has diligently studied human performance: anatomy, biomechanics, neurology and strength training so he can best optimize his athletes and patients.  Throughout

this journey, he has had to reconcile what he has learned in his medical studies and practice with traditional paradigms of strength training.  His passion is finding the most optimal way to make these two often opposing fields integrate for the best results.  To facilitate this, in 2013 he started Athlete Enhancement®, a company dedicated to educating passionate strength coaches and medical professionals about function, anatomy, biomechanics and training.


Dr. Ulm teaches strength training and rehab around the globe to coaches, educators and medical professionals.  In addition to teaching courses for Athlete Enhancement, he is a lead instructor of Dynamic Neuromuscular Stabilization (aka DNS) — regarded by many as one of the most powerful rehab approaches in the world.  He has been lucky enough to train under Pavel Kolar, the creator of DNS and a world-leading authority on function and stability.  This opportunity has profoundly affected how he assesses, treats and trains the athletes with whom he works.
