Prior to moving to Katy, TX, in 2011, Dr. Sunew practiced interventional cardiology for 10 years in northern Virginia.

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.
