Jen did a great job throughout the entire procedure. She kept me calm and very well informed. I came in very nervous for this procedure and from my initial conversation, she made me feel so much better.

Jennifer was extremely well-versed on my conditions. She was very interesting to listen to and found her advice to be spot on! I look forward to working with Jennifer in the future. I've always in the past met with Dr [last name] who I absolutely adore but I know her schedule is so busy. She took me right on time and spent quite a bit of time with me going over all of my test results.

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.
