Let me just repeat what I said in the previous question: Everyone from Dr. Yoo to his nurses to his assistants to his fellows are just terrific. They make sure of your comfort and your understanding of what is happening, and, best of all, they appreciate my quirky sense of humor. (Great audience!) No, seriously - all of my (unfortunately) many experiences with this team have been excellent. Very pleased to have the opportunity to praise and recommend them.

Disclosures

Simon S. Yoo, MD reported no external professional relationships for calendar year 2024.

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.
