About Ogubay T Mesmer

About the Provider

I was initially drawn to medicine by a need to understand how the different organs of the body function. This led me to specialize in the complex field of cardiology, which requires a detailed understanding of human anatomy and physiology.

Some cardiology patients may need significant medical interventions as part of their health journey, but my goal is to take care of your health through diet and exercise first, before starting any medications. A lot of progress can be made through lifestyle changes.

Patients often ask me what I do for exercise, and I tell them truthfully that I run on a treadmill and use a stationary bike. Both are great ways to maintain your cardiovascular health. But my goal isn’t to make you do what I do. It’s to help you find what works best for you. Nothing brings me more satisfaction than seeing a patient get better and resume their daily activities.

    He had already closed my chart on his computer when I realized I needed a refill, but he was already up, out of his chair + half out the door. He came back, looked my pill bottle + replied ok, he would refill it, but he didn't for the entire year I will need it. I was not satisfied with my experience. I think I need a new cardiologist.
