Internal Medicine Residency Program

Billings Clinic established Montana’s first Internal Medicine residency program. We welcome our 12 new residents, who provide clinical care with our staff physicians.


Visit the Internal Medicine Residency site to apply or get more information.

Following completion of medical school, a physician attends a residency program to receive additional training in a medical specialty. This includes caring for patients with a variety of diseases, and is supplemented with lectures and conferences.

“These physicians in advanced training will bring fresh ideas, new energy, and bold creativity to our inter-professional care teams,” said Dr. Bush, “They will be the leaders of care teams, improvement efforts and organizational initiatives as we design our primary care model around a clinical learning environment. Patients will benefit from strong personal relationships, and a sense of trust, safety and reliability.”

Dr. Roger Bush, Program Director, and Dr. Robert Ficalora, Associate Program Director, and a team of physicians and staff have laid the ground work for this new program.

This program is designed to address the primary care shortage by training general internal medicine physicians to stay in the region. The learning model will integrate competency-based residency training into a patient-centered medical home and the existing Accountable Care Organization.
