Rex Winters MD, is an interventional cardiologist who always had an interest in physiology. He felt that medicine—specifically cardiology—would allow him to combine his interest and knowledge to advance cutting-edge technology and high-quality care. During his training he completed an internal medicine residency, a cardiology fellowship and an interventional cardiology fellowship.

Interventional cardiology was undergoing a technological revolution during the time Dr. Winters was in medical school. As he entered the field, he knew he would be able to grow his skill sets for many years to come. Even now, interventional cardiology specialty is still advancing.

“Cardiovascular care remains highly dependent on evaluating patients in person,” he describes. “It’s that doctor-patient encounter during consultation and routine visits that I enjoy the most.” He says that the diversity of patients and cardiovascular challenges that he sees on a daily basis keeps him motivated.

His experience and skills within interventional cardiology as well as leadership and compassion for his patients are what differentiates him from others in his field. His mother was a teacher and his father a welder. He says it is the experience of his childhood that allows him to remain humble and caring in his medical practice.

Dr. Winters has been recognized annually for the past 20 years, and most recently in 2021, by Super Doctors in the area of cardiology. His main leisure pursuit is golf, but as a father of five daughters and a grandfather of four granddaughters, he says his interests are directed by his girls.

Patient Reviews

January 07, 2026
Hello, yes, I would like to know if you have a patient portal and if there's a possibility that I could have Dr. Winters call me, (PHI removed). I have a question regarding continuing taking magnesium. I can't remember what he said about it. So if you could please ask him to do that, that would be worth my time giving you this response. Bye-bye.

Dr Winters explains things in a way that are easy to understand.

What Dr. Winters 's office has done for me and in the past for a number of years has been right away taking care of me, no waiting for a week or two weeks to make an appointment. He's the best doctor that I can recall ever having my corner. I will continue to recommend him and his staff to take care of my family, which they already do, and any friends that are looking for a good doctor.
January 06, 2026
I feel that Dr. Winters, he saved my life and I think he is the kindest, most attentive person or doctor that I've ever been to. And his staff is absolutely amazing, cheerful, so informative and definitely efficient and fast. I think that they should get a trophy. It's amazing. If only other doctors were like him. Thank you, Dr. Winters.

Dr. Rex Winters is an excellent & exceptional Doctor. It is my experience that with most doctors they spend their allotted 15 minutes with you barely listening or concerning themselves with your needs. Dr. Winters and his staff have always gone above & beyond to care for me, explaining any procedures scheduled for me, any results & answering patiently any questions I may have. It's been a real comfort knowing I have such a highly qualified specialist and I would not hesitate in recommending him to friends and family!

I was very pleased with Dr. Winters, but this was my first visit, and he was very thorough. And I felt they spent enough time with me, but I'm a little slow in retaining the, you know, what I have to do and so on. So they could have maybe written me down instructions of things that I had to do before my next visit. But other than that, I really have no complaints.
