Always informative and encouraging with Dr. Jonas.

May 2026

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 have been under his care for twelve months and recommend him most enthusiastically.

Up-date: Now after 48 months under Dr. Jonas' care and monthly immunotherapy infusions per his prescription of opdivo, I would rate him 10 stars if possible. His sincere and personal attention to my case is "awesome". I actually look forward to my meetings with him.

May 2026

What a delightful experience meeting Dr. Jonas today. His bedside manner put me at ease immediately even though my concerns were potentially serious. His staff were most helpful and I received a personal call this morning as a follow up. I feel better knowing I have him on my side.

May 2026

Dr Jonas is a great provider, he has a wonderful bedside manner and is awesome explaining a scary diagnosis. He's seen me through treatments and now in remission. Still see him every six months for follow up appointments. Would highly recommend if you're in the need for an oncologist or hematologist.

May 2026

Doctor Jonas has guided me through journey with cancer from finding a tumor the size of a grapefruit shrinking to smaller than a tennis ball then going to my liver having part of it removed. He has done all of this for me for the past 19 years. What else could be said. Thank you Dr Jonas.

May 2026

Dr Jonas is very personable. He always asks about my family, as he has met most of them when I was first under his care. He makes you relax and doesn't hurry you. He gives me time to ask questions and makes sure I understand his answers. He is friendly and funny.

April 2026

Dr Jonas and his entire staff were very professional, caring, and knowledgeable.
