“Too many of my patients feel like they are being pushed through a system that talks at them instead of listening,” said Dr. Greiner. “They wait weeks for an appointment, then get fifteen minutes and a prescription. With a smaller practice, I can sit down, learn what is really going on in someone’s life, and build a plan that treats obesity, diabetes, and high blood pressure as medical conditions we can prevent and manage together, not personal failures or quick checkboxes in a chart.”

TULSA, OK, April 30, 2026 – Adults in Tulsa now have access to a new primary care model as internal medicine physician and Tulsa native, Dr. Benjamin Greiner, opens an MDVIP-affiliated primary care practice focused on prevention and relationship-based care. After almost a decade practicing internal medicine, Dr. Greiner is shifting from a high-volume panel to a smaller practice built around lifestyle medicine, longevity, and prevention-first primary care for a community where chronic disease and access gaps have made it harder to get timely, relationship-based care.

In Oklahoma, where obesity, diabetes, and cardiovascular disease rates consistently rank among the highest in the country, the demand for primary care and preventative services is even more acute across already-strained health systems. Over 75% of Oklahomans have at least one chronic condition, with heart disease, cancer, chronic lower respiratory disease, and diabetes being the leading causes of death. Against that backdrop, Dr. Greiner’s new practice is helping demonstrate how a prevention-first primary care model can give physicians the time and tools to focus on metabolic health early, rather than simply treating complications once they appear.

Dr. Greiner has seen these trends play out on the ground, from older adults juggling multiple conditions who struggle to get in to see a doctor to younger patients already showing early signs of obesity, diabetes, and high blood pressure. His new practice is designed as a direct response, giving patients the time, continuity, and preventive focus that are increasingly difficult to find in traditional clinics and that are essential to slowing the tide of chronic disease in a state with some of the highest rates in the country.

“Too many of my patients feel like they are being pushed through a system that talks at them instead of listening,” said Dr. Greiner. “They wait weeks for an appointment, then get fifteen minutes and a prescription. With a smaller practice, I can sit down, learn what is really going on in someone’s life, and build a plan that treats obesity, diabetes, and high blood pressure as medical conditions we can prevent and manage together, not personal failures or quick checkboxes in a chart.”

Dr. Greiner is particularly focused on closing what he sees as a major gap in how primary care addresses chronic disease, such as obesity, across Oklahoma, where many practices are not structured or reimbursed to give patients the time, coaching, and follow-up required to make sustainable changes. He notes that many physicians still frame weight purely as an issue of willpower, even as science increasingly recognizes obesity as a complex medical condition shaped by biology, environment, and culture.

A Tulsa native who grew up just outside the city, Dr. Greiner brings local roots and a long-standing commitment to service. He joined the Army out of high school and served as a medic, an experience that first drew him to medicine and shaped his emphasis on prevention in resource-constrained environments. Today, he continues to serve in the Army National Guard, where he was recently promoted to Major, and credits that work with sharpening his communication and planning skills.

“In the Guard, you learn quickly that you cannot wait for the perfect situation or unlimited resources,” Dr. Greiner said. “You plan, you communicate clearly, and you prevent problems before they take someoneout of the fight. I bring that same mindset into primary care here. Prevention, logistics, and honest conversations are just as important in a Tulsa exam room as they are in the field.”
