Dr Dervan and his group saved me and I'm forever thankful. At 46 years old and in pretty good shape (athlete), I was very close to dying from a widow maker. Highly recommend Dr Dervan and his team. Very professional, courteous and thorough.

Best cardiologist on Long Island. I was referred to him by a medical malpractice DEFENSE attorney. They know the great ones and the bad ones. Old school. Conservative approach but will listen to you and explain everything. Quietly instills in you a tremendous confidence in his abilities.
