Hennepin Healthcare has pioneered the field of undersea and hyperbaric medicine since opening the first hyperbaric chamber in 1964. Fellows in the Undersea & Hyperbaric Medicine Fellowship continue this tradition with clinical training in treatment of both chronic and emergency conditions. Fellows practice in our state-of-the-art Center for Hyperbaric Medicine and work with faculty who are ABMS board-certified in Undersea and Hyperbaric and Emergency Medicine. Our fellowship is ACGME accredited.
