5.0 star star star star starDr. Kalhan is calm, understanding, and caring doctor. He was able to diagnose my rare asthma in one visit that doctors for over 6 months and in the emergency room could not figure out. I am grateful to have him as my doctor and his team is just amazing.

5.0 star star star star starThe absolute best. Dr. Kalhan's care prolonged my moms life by 3 years when other Dr's had given her just months to live. He's one of the best, which is why I looked for him when I began having pulmonary issues.

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.
