Dr. William Jonas is an experienced oncologist and hematologist at Piedmont Cancer Institute and is the former President of the medical staff at Piedmont Hospital. He treats patients with all cancer types given his extensive experience in oncology and hematology.
I give Dr. Jonas the highest rating possible. He's an excellent doctor who is thorough, professional, and caring.
Dr. Jonas is incredibly kind. He explains treatment, answers all questions, tells it like it is.
Doctor Jonas is amazing. Very down to earth and nice, explaining everything and answering questions I had. Thank you for all your expertise.
I was late, but no problem. Short waits. Staff very attentive. Doc cared for a skin eruption. Way beyond his responsibility. Very supportive, caring manner. I felt very cared for when Ielt, which doesn't happen often in today's medical care.
Dr. Jonas and his entire staff are respectful, kind and knowledgeable. Time and conversation with Dr. Jonas is authentic and easy to understand. No questions are out of bounds and he always makes you feel comfortable.
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.
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.
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.
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.
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.
