Doctor of Osteopathic Medicine

Doctors of Osteopathic Medicine (DO) see patients, prescribe medications, perform surgeries, and deliver babies in hospitals, medical centers, and offices across the United States and overseas. Whether they are primary care providers or specialists, DOs use all the standard tools of modern medicine, but also have additional therapeutic modalities with which to care for their patients. Our students thrive in a culture of patient-focused care because they practice on a foundation of professionalism, benevolence, and respect. They understand that while they practice the art of medicine with their heads, they must never forget to use their hearts.
