I have been seeing Dr. Petersen for many years. He tailors our sessions to my personality, listens well, and provides good explanations for his advice_even, or perhaps especially, when he knows it isn't exactly what I want to hear_and is encouraging without being unrealistic.

Attentive personalized care, listens (and remembers) well, clearly articulates his advice and the reasons behind it, able to push back appropriately when needed. I have seen Dr. Petersen for years, and I attribute much of my success in managing my health concerns to him.

I have been his patient for more than a decade. He always keeps my specific background and experiences to mind, tailors his approach to my needs, never hesitates to provide detailed explanations when I want them (or need them), and knows when to be gentle and when to be blunt.

Disclosures

Gregory E. Petersen, PhD 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. To learn more about our Disclosure and Professional Integrity Policy, and the conflict of interest policies of our joint affiliate survey partners, please go to our Office for Regulatory Affairs Policies page.
