Patient Comments
Dr. Mesmer and everyone were excellent, kind and helpful. It was a pleasure going to Fox Chase Cancer Center. Thank you.
I am a new patient and, as yet, not subject to any treatment for my CLL. The next few visits will tell the tale: when I require treatment, how easily I may get a hold of my doctor if there is an issue, etc. I like my doctor and the medical assistants very much.
My experience has been very good and I thank you for everything
I have complete trust and faith in Dr. Messmer and his team.
Dr Messmer and CRNP [...] listened to my concerns and questions carefully before answering. That is always appreciated.
