The treatment technicians at the Radiation Oncology faciity were very helpful and always had a positive attitude. This included Ryan, Mckenze, Kelly and others who's names I don't remember at the moment. This has made the many weeks of treatment easier to get through.

Yes, Shannon, Valerie, and Dr. Barrick were all very hospitable, very loving, very kind. Beginning with Shannon, she was really, really nice and explaining things, and Valerie as well. I mean, she explained things so thoroughly that I think all of us felt comfortable discussing the matter. And I'm looking forward to seeing in the future and helping me fight this disease I have. And I really, really appreciate all your help. I really do. Me and my wife as well, the entire crew.
