I recommend him all the time. He's attentive, he's charming, he remembers the details of prior appointments. He thinks about health as an overall physical and mental picture while still engaging specific details and urgent needs in a rigorous, thorough way. He is great with timely answers to messaging through the hospital website. He does not rush through appointments and is super at conveying genuine, thoughtful interest in the person in front of him. His colleagues like working with him and often say so. Highest possible marks as a doctor and as a person.

Disclosures

Jason I. Primer, 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.
