In addition to the program requirements set forth by the ACGME, residents are obligated to meet the standards defined by the American Osteopathic Association (AOA). Our OR residents participate in osteopathic journal clubs, grand rounds and perform osteopathic manipulative treatment (OMT) in their ambulatory clinic. After completing the program, each resident will earn an extra distinction of osteopathic recognition.

Frequently asked questions

  • There are no differences in the rotation schedules, and you receive the same didactic and clinical education. You’ll have more opportunities for scholarly activities.

Will there be an extension of training for OR residents?

  • No. Residents (DOs and MDs) are expected to complete their training in 3 years.

What’s the difference between DO residents participating in OR and those who aren’t?

  • You’ll graduate residency with an extra distinction of Osteopathic Recognition.
  • The main difference will be the ability to participate in OMT clinic during your ambulatory block.

How many residents participate?

  • The program takes four to five residents per year beginning in your first year of residency.

Who is eligible to apply?

  • All first-year DO residents are eligible.
  • Interested MD residents can also apply (discuss with your course director for specific eligibility requirements).

How do I apply?

  • If you’re eligible, submit a written statement of interest to the course director to apply.

What will be expected of me?

Osteopathic recognition residents will:

  • Participate in monthly OMT didactic series/workshops and journal club sessions
  • Use osteopathic principles and philosophy during patient care
  • Participate in scholarly activity like presenting at osteopathic grand rounds

What are the benefits of this program?

  • Development and mastery in OMT techniques
  • Special consideration for chief residency positions
  • Opportunity to stand out among your peers as a leader and educator
