  • Yes, my name is [redacted] and I think that's the best hospital that I can go to. I've had three surgeries there and I love them all and I couldn't be happier with my oncologist and my blood doctor, Dr. Allen. So thank you for the chance to give them a heads up and say that I'm thrilled with all the service that I've been getting. Thank you.

  • 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]
