1 Patient Review for
Dr. Chiu

"My experience with Dr. Stephen Chiu exceeded all expectations. He is a highly credentialed, knowledgeable, and skilled surgeon with an exceptional and caring bedside manner. From our first meeting, Dr. Chiu was thoughtful and compassionate, taking the time to thoroughly explain my diagnosis and review all treatment options. He ensured that my wife and I fully understood my diagnosed cardiac condition and the procedure recommended for the best possible outcome.

Dr. Chiu’s communication skills are outstanding—he patiently answered all of our questions and spent well over an hour with us during the initial consultation to make sure we were comfortable and informed. Although this was my first experience with major surgery, I felt confident and reassured by Dr. Chiu and the entire surgical team, who were both highly professional and genuinely caring.

Dr. Chiu and his team provided excellent support throughout my postoperative recovery, including consistent communication during my at-home healing process. The Bluhm Cardiovascular Institute is truly world-class, and the care I received was exceptional. I highly recommend Dr. Stephen Chiu and the Northwestern Medicine Bluhm Cardiovascular Institute."
