Every interaction with Dr. Mumtaz from my first appointment and after has been exceptional. He listened attentively to my concerns in my first visit and prescribed tests to confirm his diagnosis. He and his staff are some of the most professional and organized medical staff I have dealt with. Messages and conversations are succinct and timely, and every concern or question is answered. They clearly have figured out how to use their portal tools in a way that provides additional support for patients but does not replace verbal interaction/conversations that are still needed and necessary in many situations.

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.
