Very approachable, thorough in his explanations, answers my questions, listens attentively and offers guidance. He is warm, caring and makes me feel he has my best interest at heart. He responded immediately by calling me right after my visit because he noticed he didn't have current lab info - this impressed me and I appreciate it. He emailed another doctor I'm scheduled to see and because of it her office called me the same day. During my visit, as a response to a question, he gave me some guidelines but also said that I should also enjoy my life. I feel that he "sees" his patients.

Korosh Sharain, MD reported no external professional relationships for calendar year 2021.

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.
