Hallo ava11,
I received my Proton treatments at the UF Proton Center in Jacksonville, FL. We chose this cancer center for two primary reasons, the first being that they offered Proton which I had decided was the route best for me, and secondly, of the several cancer centers we visited, Dr. Bryant was the only physician to actually do an exam and equally as important, he was open to discussion yet firm in his treatment recommendation(s). I included the last component as we (my wife is a nurse) were baffled and frustrated by other RO's suggesting a treatment plan, but leaving it to me to decide which option I wanted (almost like picking one from column A and then go to column B, or perhaps look at 'C', whatever you want we will do. This was quite frustrating for us.
I will however say that my Mayo visit was virtual as their Jacksonville location did not offer Proton (supposed to have it in a few years), but their MN and AZ location apparently do offer Proton. This forum provided by Mayo has been extremely helpful, both before and after my treatments (Proton and ADT).
Please do not hesitate to ask questions, everyone here is very helpful..!!
