Aside from that described above, Dr. Sita gives a patient the feeling that their personal circumstances are important and that he is there to ensure they understand and feel confident about what his plans are to help with treatment. He doesn't extend any false ideas about what to expect and he takes the time to truly clarify understandings for the patient in case they are confused. He made the experience fantastic!

He is AMAZING!!! He had suggestions, was a thinker on what should come next and p possibilities for treatment(s). He understood what I was looking for both clinically and whole body support in an integrative way and was willing to make suggestions to how that could happen. He was able to cite research to support some of the things that we talked about. I came away with a very positive feeling that this was my doctor, I wouldn't change anything.

Dr Sita took the time to sit with us and answer any in all questions we had. He also explained exactly how things would work in great detail. To top it off, we were over 30 minutes late for our appointment because the prior department ran late and he waited to arrive. Couldn't be more pleased!

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.
