5.0 star star star star starI think Dr. Cladis was fresh out of med school when I first met him. He saw me as we were expecting our fourth child. Dr. Cladis took such care of me during my whole pregnancy. He has taken care of our whole family from start to finish. I am not sure what I will do if he should retire. He is kind, caring and very knowledgeable. Our family appreciates his care.

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.
