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.
Dr Jonas is wonderful. He speaks to you in terms you can understand and is always patient. Has a great sense of humor and is relatable. His staff is courteous and competent and follow-up is superb. Highly recommend him.
Love him, he's been my oncologist for five years. Dr. Jonas is a great physician and a trusted advisor. He was an encouraging voice and a laugh too just when I needed it. Doesn't sugarcoat things which is what you need when dealing with a cancer diagnosis. Has a great bedside manner.
I want to give a shout out to my team at Piedmont Cancer Institute! Dr Jonas and his PA Scott did a fantastic job of making a difficult time more bearable. Dr Jonas was very upbeat, detail oriented and had the best treatment plan for me. I never waited long in the PCI office and the entire staff (including the Chemo team and lab) were very caring and kind. I was treated with respect and never felt rushed. I'd highly recommend Piedmont Cancer and Dr Jonas to help YOU get thru your journey and back to your life!
Dr. Jonas is an awesome doctor! Known him for 25 years and trust him implicitly! Would recommend if you need an oncologist-hematologist who cares for your safety. He is an excellent clinician with wonderful interpersonal skills.
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.
I have been a patient of Dr. Jonas for 12 years. He is the best doctor that I have ever had. He truly cares about his patients and more importantly he is a highly skilled and knowledgeable physician.
Dr. Jonas is wildly sharp and refreshingly direct. He doesn't overtalk or sugarcoat. He shows up with clarity, clinical focus, and just enough humor to disarm your fear. He balances precision with excellent bedside manner and no-nonsense wisdom. If you're seeing him for hematology, you're in brilliant hands. He listens. His entire team listens. They take your concerns seriously. The entire practice runs with such efficiency, Chick-fil-A could take notes. (I said what I said.) I've been a patient for years. I don't sugarcoat, and I only give credit where credit is due. Facts. Full trust in Dr. Jonas and his entire crew.
Dr. Jonas is perfect for this difficult specialty. His knowledge, coupled with a bright and enthusiastic personality, make a harsh medical treatment easier.
Dr. Jonas is The top Rock Star of the myriad layers of oncology. Fun, listens and all the other good qualities you need. The end
Dr. JONAS IS AN AWESOME PHYSICIAN. He was very kind and informative. He also gave great suggestions that i will follow. He was on time and tentative.
I worked with Dr. Jonas when I was a nurse at Piedmont so when I was diagnosed with cancer I knew exactly who I wanted to have as my oncologist. Not only is he an amazing clinician, he is just an all around terrific person.
Dr Jonas was very easy to talk to and answered my questions and I feel very confident having him as my doctor.
Dr Jonas is a wonderful doctor! He is caring and compassionate. He knows his stuff and makes you feel confident about your issues.
