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 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.
Dr.Jonas is the best! He really listens to you and has an answer for any questions you might have. Highly recommended.
Dr. Jonas is very personable. He takes time to get to know his patients. With the stress of dealing with cancer it is reassuring to have a kind and caring doctor.
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. He's one of the best doctors I've ever had in my lifetime.
