Dr Tosiou was respectful. He listened. He was very clear in his recommendations. He was very thorough. He spoke in everyday terms. I felt he got a feel for who I am and he cared about my good health. He was open and honest. I had no questions or concerns when I left his office. Will definitely return.

Well, I just saw the doctor for the first time. He seems knowledgeable and caring. There is nothing bad or poor to take note of as of this review. I have a colonoscopy scheduled for October so I will see then how good he is.

He’s a pleasant person and very competent. I would give him a 10 but I had great difficulty getting answers to my questions about medications prior to the colonoscopy and endoscopy. Communication with his office staff was a challenge.

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.
