I've been seeing Dr. Gruber since 1987, and he is a treasure. He's always pleasant, polite and professional, and after so many years we also enjoy a little banter when I visit. He has the calm and caring manner that gives patients a bit of comfort in an discomforting setting. He's extremely knowledgeable, and very thorough, but he does not jump to conclusions or treatments unnecessarily. He's great, and I have referred many people to him over the years, all of whom feel the same way I do!

Disclosures

Gary H. Gruber, 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.
