5.0 star star star star starDr Mueller was amazing! He figured out the source of my pain (despite years of me thinking it was acid reflux) and he is a straight shooter - letting me know his opinions and advice on how to treat my issues. He also went out of his way to get me scheduled for the procedure that alleviated my pain on an expedited basis.

5.0 star star star star starClear spoken. Extremely knowledgeable about his patients and his field of medicine. Personable and takes the time needed to explain a term of his diagnosis. He has many more years of practice and experience ahead of him. I’m confident that he’ll do and give his best. I’m continuing on as one of his new patients..
Disclosures
Charles Muller, MD reported no external professional relationships for calendar year 2023.
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.
