Going to meet my Neurologist for the first time today I honestly respectfully didn't expect too much because we are just meeting and I assumed it would be standard questions pertaining to what was in my record. On the contrary. His professionalism, knowledge and personable attitude brought me comfort. I felt safe and for the first time in a long time I had hope rekindled. I'm excited to see what my future holds being seen at Northwestern. From the front desk to the time I departed! Thank you everyone very much! I deeply appreciate you all!

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.
