Type of Practitioner: 

James F. Loomis Jr., M.D., M.B.A., received his medical degree from the University of Arkansas, where he was elected to the Alpha Omega Alpha Honor Medical Society and graduated with honors. He subsequently completed his internship and residency in internal medicine at Barnes Hospital in St. Louis, Mo. In addition, Dr. Loomis received an M.B.A. from the Olin School of Business at Washington University in St. Louis. He is board certified in internal medicine and has also completed the certification program in Plant-Based Nutrition from Cornell University.

Dr. Loomis has served as team internist for the St. Louis Rams football team and the St. Louis Cardinals baseball team, as well as tour physician for the St. Louis Symphony Orchestra. Before coming to the Barnard Medical Center, he practiced internal medicine at St. Luke’s Hospital in St. Louis, where he was also the director of prevention and wellness. He was also on the clinical faculty of the department of internal medicine at Washington University School of Medicine.

When not practicing medicine, Dr. Loomis enjoys reading history books, cooking, and teaching plant-based cooking classes. He also enjoys running, biking, and swimming, and has completed numerous half marathons, marathons, and triathlons.




After meeting all three physicians at the Barnard Medical Center, I made a new patient appointment with Dr. Loomis. I was not displeased with my then-primary care provider. Rather, I was looking for a doctor who shares my belief that food is medicine and diet has a direct impact on health. Dr. Loomis was pleasant and he spent a lot of time with me. He explained his background, and his personal experience with a plant-based diet and how the results he experienced changed the way he practices medicine. He gave me a brief exam, but the bulk of the time he spent with me was getting to know me: not just my medical history (although we did go over that in detail), but really getting to know me. He ordered some routine blood tests, and also a B12 test, even though I had not been on a plant-based diet for very long. I was surprised by that one because I read that it generally takes a vegan about 5 years to become B12 deficient. Sure enough, Dr. Loomis was correct: one of the medications I had been taking (which he took me off) was interfering with B12 absorbtion, and my B12 level was low. Once my lab results came back, he provided the results to me electronically, along with a few suggestions. I responded with a question, which he fully answered in a timely manner.

Dr. Loomis made me feel like he cares about me and my well-being. It is obvious that preventative medicine and wellness are his passions. Jim Loomis is not a doctor who has experienced burn-out and is just trying to make a living practicing medicine.

I can't say enough good things about Dr. Loomis and the Barnard Medical Center. I would see any of the doctors there. The reception staff is friendly and pleasant. The dietitian I met with (Cameron Wells) was knowledgeable and pleasant. There is a in-house LabCorp phlebotomist to draw blood for labs. I'm very pleased with my experience thus far, and I highly recommend Dr. Loomis and the Barnard Medical Center.
