Dr. Summa listened to my concerns, answered my questions, and reviewed my past tests thoughtfully. He was able to diagnose my issue, prescribe medication that could address my symptoms, and prescribed blood tests to eliminate other possibilities for my symptoms. I did not feel rushed during my appointment, and all my questions and concerns were answered. I would recommend Dr. Summa to other people in my life.

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.
