Dr. Mercader was very responsive to my emergency situation, in which I needed an ICD. And over the last 6 years he has more than met my needs as my physician. He answers my questions and provides reassurance when I need it. Recently, he went well above the call of duty when I needed a procedure in gynecology that involved electrocautery. He came to my aid within a few minutes, and stayed with me throughout the procedure. He was calm and reassuring. He is a cardiologist with a real heart!

Why Does Experience Matter?

Even specialists specialize. One orthopedic surgeon might do nothing but hip surgeries, while another does nothing but knees. If you want the best possible care, it’s critical to match your medical need with the doctor who truly specializes in treating it.
