Dr. Losito is on Barry's faculty and is the team podiatrist for the Miami Heat.

I also know that Marque Allen in San Antonio is the podiatrist to the Spurs as well as the WNBA team there; he spoke at a AAPSM seminar here in Miami and his lectures were excellent and very informative.

From listening to a couple of Losito's presentations and lectures, it seems that he believes that the main reason most DPMs aren't more involved in sports medicine is the sizable time commitment required and high expectations for limited financial returns. He sounds very satisfied with the challenge and expectations which come with treating athletes, but he jokes that most podiatrists want nothing but heel pain and a few hammer toes since those cases and outcomes are easier, more predictible, and more profitable. As a former AAPSM president and the director of what I believe to be the only fully approved DPM sports medicine fellowship, I think he'd know. I look forward to more lectures in his courses as I become an upperclassman. He is very well smart and respected, and he still remains a funny guy who makes learning fun.
Unfortunately, I think that many high level fields such as sports podiatry, pediatric podiatry, and podiatric research are not attempted to any great extent by the majority of DPMs. The additional training for these arenas is extensive and the fellowships often pay an even lower salary than DPM residents make. It's easy to say right now that I want the best training and plan to do a fellowship someday, but will I change my tune if/when the time comes that I'm a 3rd year pod resident with multiple $100k+ job offers as opposed to a $25k fellowship...???
