Dr. Mulcahy is phenomenal! It's so amazing to have a doctor that takes her time, doesn't make you feel rushed, and answers the questions I forget to ask. She does all that and more with professionalism, years of knowledge, experience, and care. I am so fortunate to have found Dr. Mulcahy.

Dr. Mulcahy is not only incredibly competent, but her bedside manner is unmatched. On every visit, she listens intently and takes my concerns seriously. She engages other specialists to weigh in on my care as needed behind the scenes, ensuring that my whole heath is being taken care of, and not just the oncology portion of my care that she's responsible for. She communicates in a way that is easy to understand, presenting the facts of my case directly and rationally. She is patient and takes all the time necessary to answer my questions; she has never made me feel like she needs to rush to another appointment. Even when she's had to share bad news, I've left her office feeling reassured that there is a plan to address the issue and confident in the plan & team.

Disclosures

Mary F. Mulcahy, 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.
