Dr. Dennison is understanding, and realizes that symptoms can affect treatment and progress. He's an excellent listener, willing to discuss and explain treatment options and pros/cons/side effects, he meets you where you're at intellectually, and has been really supportive and kind throughout the ups and (mostly) downs of my conditions. It's hard existing in a world not made for your neurotype, constant challenges and failures, however Dr Dennison makes it just a lil bit easier, and I appreciate him for it.

Disclosures

Thomas A. Dennison, MD reported no external professional relationships for calendar year 2024.

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.
