Testimonials from Dr. Jonas's Patients

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.

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.

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.
