5.0 star star star star starShe was very nice to talk to and made sure I understood the procedure prep, benefits, risks, alternatives and how I would get results. She took time to answer all my questions and made me feel comfortable with the procedure.

5.0 star star star star starShe was unbelievably good!!! I haven’t had someone giving me the time, attention and care ever in the GI department. She listened to everything I said, explain all my questions, gave me a variety of options and calmed my fears. Everything with a smile, warmth and outstanding presentation. If I ever was to give a 10, she deserves. So grateful I got her to take care of me.

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.
