If one must have the services of an oncologist Dr. Bill Jonas would be an excellent choice. Personable with an excellent "bedside manner", he at the same time is most professional and up front with his diagnosis and planned treatment in a most calm and non threatening way. I recommend him most enthusiastically. Up-date: Now after more htan 5 years under his care and prescribed monthly immunotherapy infusions of opdivo, I would rate him 20 stars if possible. His sincere and personal attention to my case is "awesome". I actually look forward to my meetings with him.
