5.0 star star star star starA free spirited and liberated attitude. I was able to understand the purpose of everything explained to me. Medical is a serious part of my life. Everyone needs a doctor that he or she feels as though they can trust

5.0 star star star star starDr. Chacko really seems to care about providing personalized healthcare, and his demeanor is very caring and sincere. He is the first primary care physician I have had who asked for a follow-up a month later to check on the progress of the condition I had first sought healthcare for---I was actually in-between primary care phsyicians, because my last one left the practice. I had an issue come up, and Dr. Chacko was the PCP who had an opening and was able to see me on short notice. I appreciated my interactions with him so much that I am making him my permanent PCP moving forward.

5.0 star star star star starDr. Chacko is very personable and does a great job at explaining health issues, preventative care, and the rationale behind lifestyle recommendations that he gives. I very much felt more like a person than a patient during my annual _ and I mean that as a great compliment.
Disclosures
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.
