Dr. Colohan's Story

Dr. Shannon Colohan became an oncologist because she "enjoys the humanity that cancer care brings to medical practice. In particular, I like working with cancer patients to help improve their sense of well-being and restore a sense of ‘normalcy’ during a stressful period in their lives."

Dr. Colohan has a background in epidemiology and a strong interest in clinical outcomes research in patients requiring reconstruction as a part of their cancer treatment.

Outside of work, she enjoys traveling, the arts, theatre, reading, or just spending time with friends and family.
