He was kind, patient in making sure my daughter was "healthy" before sending us on our way. He didn't rush us out.

Dr. Zun was also very pleasant. He is very knowledgeable, thorough, and took the time to both listen and explain details to us to ensure we understood everything from start to finish. His recommendations were genuinely aimed at resolving our concerns (not every doctor seems to care much - particularly in immediate care locations). Dr. Zun is an excellent doctor and we sincerely appreciate his outstanding level of care.

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.
