William W Dexter, MD

Family Medicine, Sports Medicine


As someone who has been active and athletic my whole life (running, rowing, biking, rugby, golf, hiking) and raising three active kids - I appreciate how hard it can be to have an issue that limits your ability to do the things you love to do. I am devoted to trying to help patients get and stay active whatever your problem or barrier to staying active either in work or play, weekend warrior to competitive athlete. As a Primary Care Sports Medicine Specialist I am interested in both medical issues that limit activity (breathing, concussion, illness, etc.) and in non-surgical approaches to your orthopedic problems. Working with folks to identify solutions to their problems that will help those individuals lead more active, comfortable and healthy lives is my passion.
