I have decided to ask Dr. Nicholas to be my pcp. In our first appointment he spent about 90 Minutes to get to understand my health issues. Knowledgeable, thoughtful,, interested and has excellent patient skills and demonstrated genuine caring.

I have total faith and trust in Dr. Nicholas. I believe he is an excellent physician who is very concerned about the well being of all his patients. I am fortunate to have been his patient for many years.

my two most recent appointments resulted in waits of 58 minutes and excess of 60 minutes respectively prior to seeing Dr Nicolas. this would appear to be an overbooking issuel. once is a fluke; twice is a pattern.

John has been a 10+ with me and my wife, who he also provides care for. I’ve had a lot of Doctors over the years and he is thorough and interested in what you have to say. He has provided excellent advice for a variety of situations for both of us.

First time seeing Dr Nicolas. Spent longer than I expected going through history and providing a thorough annual exam. Solid advice and recommendations. Looking forward to working with him on my health going forward.

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.
