      I have no words to describe my appreciation for Dr. Lewin. He has been seeing our little for the past 2 years. His bedside manner is excellent. He is very empathetic and genuine. We were thinking about relocating to a different state but decided no to because we do not want to be seen by another physician.

    • Christine Auburn 10.27.20

      I saw Dr. Lewin from 2002-2012, until I had to move to UW as an adult. When we found out our two sons have Marfan syndrome as well, Dr. Lewin was the first and only person we thought of to care for them. Hands down, he is the best physician we have been to.

    • Ambre Sammamish 06.26.20

      I met Dr. Lewin around 2004, and saw him until I had to move to UW Medicine in 2020. He literally saved my life. I had a very rare aortic aneuryism and Dr. Lewin was very diligent about my care, and made sure I got the best possible surgeon to remove it. I would 100% reccommend Dr. Lewin. He is by far one of the best doctors I have ever seen, turely cares about his patients, and is very kind and understanding.

    • John Newcastle, WA 11.05.13

      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.

    • R Redmond, WA 02.29.12

      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!

    • Christine Covington, WA 03.23.11

      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!!
