More physicians should be like Dr. Posner who is both smart and caring. When you are with him, he gives as much time as you need answering all questions, and enlarging the conversation to areas not thought of by the patient(me). The hospital is truly fortunate to have Dr. Posner

He made us feel welcome and very comfortable. He spent time explaining what the course and length of treatment would be. He even gave us the option of a shorter version of treatment. He made sure that I knew it was my choice about accepting treatment. My husband and I walked away knowing that I was in good hands with Dr. Posner.

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.
