As a competitive runner, John, a certified personal trainer and running coach, realized most runners will likely encounter injury at some point in their journey. While many running coaches can develop a solid training plan, John has successfully integrated traditional run coaching with cutting edge strength and movement training. In addition to his B.S. in Kinesiology from Penn State (’00), he's currently Center City Philly’s first and only Neurokinetic Therapy® Level 3 practitioner which enables him to unravel movement compensations that are often the root of many movement related problems like pain or tightness.  He is a certified ACE Personal Trainer, a Functional Movement Screen Expert, a Road Runner Club of America certified running coach, and Precision Nutrition Level 1 certified.
