Mary-Katherine is an exceptional Advanced Practice Provider. She listens to all of my many concerns and responses kindly, calmly and without rushing. She is always ready in the background, when I need an order or prescription electronically. It would be hard to l choose one of Mary-Katherine's best qualities! I ask a lot of technical questions, and she is a very good teacher who uses both visual props and verbal acuity.

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.
