5.0 star star star star starI respect her. She surrounds herself with an excellent staff. The is very professional and knowledgeable,but speaks from the heart and listens to me. She is patient and kindhearted. Everything speaks that she would treat her parents just the same. She has a way of communicating with me and has a way to convey to me she values me as a person. I know she has many other patients, but I could I have confidence that she do the best for my brain condition. She makes a difficult situation manageable and respectful.

Disclosures
Tamar D. Gefen, PhD reported no external professional relationships for calendar year 2024.
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. To learn more about our Disclosure and Professional Integrity Policy, and the conflict of interest policies of our joint affiliate survey partners, please go to our Office for Regulatory Affairs Policies page.
