About John Arthur Nash, MD

Care Philosophy I chose to become a physician because of my love of science and my desire to work closely with others. I was drawn to cardiology because the heart is often thought of as providing the vital force which keeps us alive. I strive to work closely with patients and their families, to help them understand and manage their heart condition in an effort maximize their physical and emotional well-being and enhance their quality of life.

        Dr. Nash really listened to my concerns and is working with me to help me on my medication and have a better heart. He was very good. I'm so glad that Hentham is still my insurance with Mercy because I didn't know what I was going to do. So I really like Dr. Nash.

        Dr Nash is an excellent communicator. I kept mixing up blood pressure treatment and cholesterol treatment. He patiently walked me through it, which is very helpful. We've had a frustrating time with UHC but Dr Nash has aggressively advocated for me. Hopefully plan B will work.
