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've have several appointments and encounters at Piedmont Cancer Institute and I can truly say this encounter was above my expectations. I've had the pleasure of obtaining assistance from Trenell. Throughout my appointment Trenell made it their business to answer and questions or concerns that I may have had as well as provide reassurance that I would be taken care of and seen in a timely and effective manner. I'm eternally grateful to Piedmont Career Institute and the amazing staff for always looking out for its patients.
Top notch care, seen promptly, Dr. Jonas was fantastic, extremely knowledgeable, reassuring, and on top of everything. Entire team of providers from Scott the NP, to the receptionist and lab personnel, I couldn't have asked for a better experience.
Dr. Jonas actually LISTENS to you and tries to address your concerns. He's straight forward with you and doesn't beat around the bush. I appreciate that about him. Great doctor!!!
Dr. Jonas was . . . compassionate and confident and reassuring. I love Jackie and Lucille. Compassion pours out of them.
Dr Jonas and his care team are exceptional. I reached out over a busy holiday week after a disappointing conversation with another Dr's office. Dr Jonas was personable and caring at a time when we needed it the most. I couldn't recommend him more highly or thank him enough for his care.
Dr. Jonas is a very smart Dr. that helps you with your health more than hematology issues. Hes one of the best doctors Ive ever had in my lifetime.
This Oncologist has been taking care of me for 13 years with stage four lung cancer. If I were to refer any cancer patient, I would refer them to him. He's a very straight shooter and has a sense of humor as well
As always, Dr Jonas was cheerful, supportive, and efficient while answering all my questions.
Visit was a recheck and Dr Jonas had done his research! He knew my previous "numbers" and explained what I was to do to feel better. He made suggestions for me. I always feel that he is on top of everything going on with his patients! He was my husbands Doctor and we both were more than satisfied with his care for him and now I feel I have complete confidence in diagnosis and treatment. He is always easy to talk with and cares for his patients, answers any questions I may have also! Wouldn't change Doctors for anything, he is the best! He truly knows his profession very well!
Dr. Jonas is personable and thorough. Even with seriousness of cancer his attitude is one of care and hope. Always positive.
I was welcomed well as usual. Dr Jonas is an exceptional Dr. He is very kind and welcoming. He is very thorough in explaining my health issues. I would recommend my friends and family to Dr Jonas if needed.
