What do a performance strength coach and a chiropractor have in common? For starters, they are both life-long athletes, each of whose personal experiences taught them that there was a gap in performance training and health management.


Chicago Sports Institute
Dave Hollinger and Dr. Josh Akin combined their respective expertise and passions to fill the gap that they saw between injury management and performance training. They created Chicago Sports Institute to effectively combine performance training, sports medicine and integrative health. In doing so, they have allowed athletes and active individuals to achieve their athletic and lifestyle goals.
