About Me

Dr. Sunew is triple-board-certified in Interventional Cardiology, Cardiovascular Disease, and Nuclear Cardiology. He is listed among Top Doctors in 2013 and 2014 in both HTexas Magazine and Houstonia Magazine. He was born in Connecticut and grew up in New York. He attended Amherst College in Amherst, MA, and SUNY Downstate School of Medicine in Brooklyn, NY. He completed his internal medicine residency and cardiology fellowship at The George Washington University Medical Center in Washington, DC, and an interventional cardiology fellowship at Northwestern University in Chicago, IL.

Prior to moving to Katy, TX, in 2011, Dr. Sunew practiced interventional cardiology for 10 years in northern Virginia. He held many leadership roles with the Inova Health System, including Medical Director of the Cardiac Cath Lab at Inova Alexandria Hospital and Chairman of Inova Cardiology Quality Steering Committee. He was Regional Leader for northern Virginia in the Virginia Heart Attack Coalition.

Dr. Sunew offers the latest and most innovative treatments in his field, including transradial cardiac catheterization. This involves performing the procedure through the radial artery at the wrist instead of the traditional approach through the groin at the top of the leg. The radial technique has the advantages of less bleeding risk and improved comfort for the patient.
