This doctor is distinguished by his humanity above all else. He is highly skilled in his work and has extensive experience as well. For me, he is the best doctor I have ever dealt with, and I will definitely recommend him to others

I love a doctor who talks to his patients and not at them. This is my second colonoscopy with Dr. Kosmala. I specifically asked to have him do my colonoscopy given that he had done a previous one and at that time told me that there was a pollup that was that needed to have a specialist remove. I appreciate his honesty. Also, he took the time to answer all of my questions. Without question, I would highly recommend him.

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.
