Not sure yet. I only met him for a consultation but I felt that he was very thorough and interested in my particular case. He asked me a lot of questions and seemed genuinely concerned about my symptoms. He offered various tests but was leaving it up to me to decide. With his extensive experience, I feel that I am in "as good of hands" as I was with Dr. Troy.

Disclosures

Alexander S. Tosiou, MD reported no external professional relationships for calendar year 2021.

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.
