I currently receive the best care medically available with my primary care physician, Dr. Nicolas. I would never even contemplate even an opinion elsewhere. Dr. Nicolas takes extreme care, discusses all my medication and does the most thorough exam in the most professional manner. A gentleman and one of my most respected professionals I could hope to have met and receive such constant excellent care from.

For the reasons stated above: My primary care physician, John D. Nicolas, MD spent more time with me, during my recent annual physical examination, than *any* doctor has in memory. Not just time, but quality time - getting familiar with my and my immediate family's health history, noting important/related facts and observations and asking pertinent questions - before doing a comprehensive and thorough examination. Upon exit, he even walked me to the lab for lab work - a thoughtful gesture. I walked out feeling seen, heard and assisted - a rarity in my experience. John D. Nicolas, MD has a calm, nurturing personality and made me feel comfortable to share and ask questions that were on my mind. I would recommend John D. Nicolas, MD as a primary care physician/internal medicine doctor for care to anyone.

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.
