The osteopathic curriculum involves four years of academic study, with an emphasis
on preventive medicine and holistic patient care. DOs serve a one-year internship,
gaining hands-on experience in family medicine, internal medicine, obstetrics-gynecology,
pediatrics and surgery. This experience ensures that osteopathic physicians are first
trained as primary care physicians—even if they plan to pursue a specialty. Many DOs
then complete a residency program in a specialty area, which typically requires two to six years of additional training.
