Jennifer, is a very lovely person, who cares about everybody that works with Northwestern. She's brilliant and very understanding. Jen helps patients and truly cares about each one. For example, previously, I used vitamins for years. We should only take them for issues within your body. Jenn sent me a message to stop. Thats the direction, I'm moving to. She helped me get better with cancer. She will help every patient if needed. Thank you Jenn for everything you've done for me! Xo [Patient's Name]

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.
