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 is the best cardiologist I have ever had. I'm 76. Never has anyone taken the time to explain my problems with my heart or how to fix them like he did. Thank you Dr. Kay!
