She is a delight to work with because of her personality. She keeps good yet short notes so is able to pick right up from the history that matters to her patient's story. She is willing to answer duplicate questions and ask even after that if there are any more before she leaves. As she exits, she reminds me that she and her staff are always available if something more comes up.

Dr. AHN is a great surgeon. She is very thourough. She listens to my concerns and is very patient with me. She explained my pathology report and together we planned the next steps in my Journey of breast cancer.

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.
