I was extremely lucky to have Dr. Jill Allen as my medical oncologist. She is extremely kind, responsible, competant , and everything you would want in a person and a physician at a scary and vulnerable time.

I just felt that she was, Dr. Jill Allen was short with her answers in that I really still don't know exactly what's going on with me. And I don't know if I'm going to feel better after chemotherapy. It was just too quick a visit. It was not, she said very little side effects. I went home and read the literature. She handed me literature to read. It was not a great experience. It's not like it was a super bad experience, but it was not a great experience. I had a lot of questions that didn't get answered [redacted]

Loved Dr. Allen. She had great bed side manners and listened attentively. The radiation oncologist, on the other hand, made some comments that came across as condescending even though she was competent and explained things clearly.

I have had the benefit and pleasure of being treated by Jill Allen since my cancer diagnosis more than 4 years ago. Dr. Allen is not only very smart and knowledgable, but she cares deeply about what she is doing and goes the extra mile to be sure that I am getting what I need. I had the need to see her quickly and she went out of her way to get CT scans and blood work done for me on an expedited basis and to see me very quickly as well. I am very grateful to her.
