Odilichi Ezenwanne, MD (PG3)

Odilichi Ezenwanne graduated from the University Of Ibadan College Of Medicine in Nigeria. After medical school he was employed as a medical officer providing community health services to a number of hard-to-reach underserved rural settlements. He notes that this provided him with a huge opportunity to gain invaluable experience in managing health facilities in very low resource settings.

After a few years in this position, an intense desire to improve the quality and range of services he was providing eventually led him to the University of Connecticut where he completed two years of preliminary surgical training. He returned to Nigeria where he worked in Abuja in a private practice with a bias for preventive medicine as a manager and provider of clinical services. He also spent time as a volunteer with a faith-based organization that provides free medical counseling and carries out medical outreach programs to underserved communities around the Abuja metropolis.

Richard Crawford

Richard Crawford, MD (PG2)

Rich grew up in Northern California and majored in biomedical engineering with a dash of finance and economics at UC Berkeley.  Upon graduating, he worked two years at the UCSF Memory and Aging Center developing neuroimaging techniques to examine the intrinsic connectivity of the healthy brain and its application to neurodegenerative disorders.  Then, he moved to Portland, OR, where he worked with the Coalition of Community Health Clinics to assess community needs and also began an anti-human trafficking initiative, Tomorrow’s Hope, which emphasized prevention and early intervention strategies.  While completing medical school at The George Washington University he participated in the health policy track where he engaged in the analysis of CHIPRA pediatric quality measures and their association with expenditures and care delivery models as well as an evaluation of tele-mental health technology used in Veteran and American Indian populations. He has continued his training in Washington, DC, and is in the process of completing his second year of psychiatry residency at Georgetown. His primary interests are in the fields of neuropsychiatry and addiction medicine, the financial aspects of health care, and adapting the inherently multidimensional approach necessary for psychiatric care to challenges in population health.

Rich is new to the Great Lakes Region, and likes that Madison has culture and a food scene rivaling larger cities, but in a more intimate environment.


Margaret Nolan

Margaret Nolan, MD, MS (PG2)

Maggie’s public health path began directly after graduating from Princeton. She decided to attend graduate school at Harvard School of Public Health, studying social epidemiology and human development. She loved public health but still felt a calling to medicine, so she ended up at the University of Chicago Pritzker School of Medicine for medical school and then Mayo Clinic in Rochester, MN, for two years of residency in Family Medicine.  She then switched into a research track and is currently a Senior Research Fellow doing tobacco research and intervention program design for the clinic. Throughout these years of training, she has been active in the medical humanities in various ways—as a college English major, she enjoys trying to integrate literature and medicine.

Maggie grew up in Minneapolis, and is a Midwesterner at heart, despite having lived 8 years on the East coast. She and her husband have two active and mischievous toddlers that keep them busy. When they are not working, they are outside like true Minnesotans attempting a variety of sports in all seasons.
