– Residents –

Our multifaceted support system is the most consistent strength identified by our residents in their exit interviews. We seek to provide practical support, including educational, financial and patient care resources. Our carefully designed support creates a foundation for community between the residents and faculty. This is achieved through a two-week orientation; Winter and Summer retreats; group Bible studies in faculty homes, residents and/or their spouses; intentional mentoring and faculty/behavioral advisory relationships. In addition to practical and structural support, In His Image desires that each resident be provided excellent personal support. Through mentoring, counseling and marriage support, our residents are provided assistance in balancing their personal and professional commitments.

Our residents enjoy spending time with each other. They are committed to solid family medicine training and are eager to explore what it means to be a physician with a global health perspective. The residents work as a team in an encouraging atmosphere. Though their training is rigorous, schedules ensure time for family, personal spiritual growth and recreation.

“This should be the toughest three years of your medical training, and you will want to do that in an environment where you are cared for as a person and can grow in your faith.”
Dr. Ashley Hildebrand, Assistant Residency Director

– 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.

Tulsa Information

We love calling the city of Tulsa home, with its numerous parks, many nearby lakes, over 1,000 restaurants, and extensive retail shopping. One of the largest parks, spanning 100 acres along the Arkansas River, is the Gathering Place. It was chosen by TIME magazine as a top 100 greatest places in the US. We have 135 parks and trails in the Tulsa area. Many say it is like a big city, but with a small-town feel. Tulsa is a city in America’s heartland where you can feel good about bringing your family.

Tulsa embraces diversity. There is a plethora of churches to choose from, as well as local businesses and organizations that are dedicated to sharing our cultures. Tulsa is also a place that highlights the arts! It is home to 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 listed as one of the Top Ten Places to Live by “Relocate America.” Visit these websites for more information: travelok.com and visittulsa.com.
