Dr. Mark Lewin is tops in his field. With incredible patience he helped us through the process of understanding our daughter's complicated congenital heart diagnosis in early 2009 and answered every last question we had and some, multiple times. Because of him we were able to make the best choices of care for our daughter and we consider ourselves extremely fortunate to have him as our daughter's heart doctor for nearly the past 5 years. He is an amazing professional and kind man. Any parent would be lucky to have him as their child's doctor.

We have seen Dr Lewin for our 30 week baby fetal eco diagram. We also met him in the hospital when our son was hospitalized for heart failure. His bedside manners is awesome. He gives lot of statistics to make you feel comfortable and get ready for the complicated surgeries of your baby. Wonderful doctor!

I've been Dr. Lewin's patient for nine years now, and dread the day that I have to find another doctor to take care of all of my heart issues. I'm especially impressed with the care and compassion he shows for all of his patients, and the dedication he has to his work. His bedside manner is wonderful. He is overall a fantastic provider!!
