– graduates –

Over 290 doctors have graduated from our residency program. Fortunately, we are able to keep in contact with most of them through our In His Image Alumni Association. They are working in a variety of locations and a variety of medical practice settings. Although only 10-15% of our residents come from Oklahoma, nearly 25% of the IHI graduates have decided to practice medicine in Oklahoma – many of whom are serving in inner city Tulsa and the greater Tulsa area. Fifteen percent of IHI graduates are currently serving as long-term global health workers and another 10% are serving in Indian Health Service and other underserved populations in the U.S. Most who live in the states are actively involved in domestic or short-term international health outreach, and many are involved in medical education as part of their careers.

– Faculty –

We believe if residents are well trained and fully trained, they will become like their teachers. Therefore, the caliber of our faculty, our teachers, is of utmost importance. Every In His Image faculty member is passionate about their faith and view the practice of medicine as a calling and ministry. They are all active in clinical practice to ensure up-to-date skills and knowledge and to serve as a quality example for training residents. In addition to our core faculty, about 50 partner physicians in the community teach our residents their specialty during rotations.

– city –


We love calling the riverside city of Tulsa home, with its numerous parks, many nearby lakes, over 1,000 restaurants, extensive retail shopping, plethora of churches and genuinely friendly people. It is a progressive city in America’s heartland where you can feel good about bringing your family. Tulsa is home to two world-class art museums, ballet, opera, theatre and an outstanding philharmonic orchestra. Another very real benefit: salaries stretch farther in Tulsa. While the quality of life here is high, the cost of living is comfortably below the national average.

Tulsa is also an important center of business and technology with thriving businesses in energy, technology and communications, finance, medicine, education and transportation. “Newsweek” named Tulsa one of ten strong emerging technology cities. “Southern Living” magazine named Tulsa one of its “Five Favorite Southern Cities.” Tulsa was selected as one of America’s Most Livable Communities by the Partners for Livable Communities and was chosen one of the Top Ten Places to Live by “Relocate America.” Visit these websites for more information: oklatourism.gov and visittulsa.com.
