5.0 star star star star starI feel he takes the time to listen to what is ailing his patients and figures out the best possible solution to resolve any issues. Makes sure all (I mean all) test are done to the patient before leaving and then makes sure there is a follow up set.

5.0 star star star star starDr. Nicolas has been my primary care doctor for almost 3 decades - and if you meet with him - you will know why I rate him a 10. He is extremely thorough and thoughtful and keeps up with the latest in medical treatments and protocols. Almost always has a medical resident or student with him - which shows you he is a great example as well. Have referred at least a dozen other patients his way over the years - all extremely thankful for helping them find a great doctor.

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.
