Obstetrics & Gynecology Medicine Residency Program
Program Director Welcome
Welcome to the Oklahoma State University family, home of the Obstetrics & Gynecology
Medicine Residency! We hope you find our website full of specific information about
our residents, faculty, alumni and staff. All of the information about our curriculum,
salary, benefits and training facilities can be found throughout this website. My
hope is that you not only find the information needed but that you are able to see
what makes our training environment at OSU such a wonderful place as you accomplish
your goals and dreams of becoming a Obstetrics and Gynecology physician.
Our academic sponsorship by Oklahoma State University, combined with our status as
one of the largest training hospitals in the United States, means that our residents
get the “best of both worlds.” Our diverse and extremely talented faculty wear many
hats: they teach at state and national meetings, are recognized leaders in the community
and are passionate advocates for whole-person-based primary care. All of our residents
learn comprehensive women’s health care, which includes surgical training, community
medicine and tremendous experience in clinical medicine-based hospital care. At the
same time, our Oklahoma State University connection gives our residents access to
significant academic resources and medical student teaching opportunities right here
in Tulsa, a haven of Southern comfort and cosmopolitan style in the expansive Oklahoma
We look forward to sharing our enthusiasm with you. We are passionate about what
we do and whom we serve. When we ask residents, faculty, and staff what they most
like about our residency program, the answer is universally “the people” and the sense
of belonging to a learning community that feels like a family. We want to continue
to attract people who share our dedication to serving those who need it the most.
If you are committed to caring for the underserved and seek training in an academically
rigorous yet “hands-on” learning environment, please be sure to contact us.
