Dr Andersson has outstanding communication skills. She answered every question in depth. She made me feel comfortable in asking questions. She did research after my appointment to assist me in screening for pancreatic cancer (due to a genetic mutation). Considering I will be following this provider for many years due to my liver disease, I feel very lucky that I found MGH and I will be treated with the best providers and the best care for the rest of my life.

Dr Andersson is one of the best physicians I have ever encountered. She is extremely kind, smart, thorough and listens to all concerns. She explained a short term plan of diagnostic tests and how and why they might be done. My first experience with her was 13 years ago where she quickly helped me obtain rapid care for a serous surgery that I needed to have at that time. She has remained a very trusted and valued doctor in my care group.
