David made the decision to leave the pool deck but stay
in training. As a trainer/coach, he has been working with
individuals and groups to help people achieve their goals. Goals in

science. Looking beyond a training certification is his degree in
Biology and a minor in Fitness Specialization.
As an adult athlete David has a history of competing in
obstacle racing, road races, triathlons, open water swimming and
