Dr. Tsay was more informative than any other doctor I've been to. She explained things in detail and answered all my questions clearly. She was friendly and enthusiastic, and by her mannerisms I came away thinking she loves her job as a cardiologist. She spoke very clearly which was a plus since I have trouble hearing even though I have hearing aids.

It was my first time meeting Dr Tsay. I really liked her demeanor, knowledge, bedside manner and approach to my care. Dr Tsay took the time to review my medical history, before my appointment. She was friendly, and even drew out a diagram for me, explaining my heart condition. She answered all of my questions, and I left feeling confident that she understood my concerns/needs. A great bedside manner, is so hard to come by, these days, and she was very friendly and positive!

External Professional Relationships

Pharmaceutical, device, and biotechnology companies frequently collaborate with basic scientists and physicians within an academic medical center to help advance science and improve patient care. These relationships are important in achieving scientific breakthroughs and in establishing the effectiveness and safety of promising new therapies. In order to assure objectivity in clinical research and patient care, the Northwestern University Feinberg School of Medicine (Feinberg), Northwestern Memorial HealthCare, Children's Hospital of Chicago Medical Center, and the Shirley Ryan AbilityLab have adopted integrity policies that require research and clinical faculty (in full-time, part-time, and unpaid/voluntary categories) to report compensated and uncompensated external industry relationships. Patients are encouraged to discuss these disclosures with their physician as well as to inquire as to how these relationships are overseen by Feinberg.
