Cardiology

Accepting New Patients

Meet William

I am trained in both adult and pediatric cardiology, and I love the variety of seeing the full spectrum of heart disease. I am especially interested in congenital and valvular heart diseases, as well as preventive cardiology. I see teenagers 13 and up who have concerns about their heart, and I speak Spanish fluently. I enjoy serving Hispanic patients and doing visits with them in their native language.

Dr. Kay was very nice and listened to me. He told me why he was suggesting the test instead of just coming in and saying I'm ordering this and that. I felt he really cared about doing the best for me.
