Testimonials from Dr. Jonas's Patients

October 2023

Outstanding physician and staff. Took the time to explain everything about my condition and next steps. Professional and timely. Staff was excellent. Sincere in their approach and my well being. The best.

October 2023

Dr. Jonas is very professional with a great sense of humor. He seems to be one step ahead in anticipating what is needed for clinicals and puts those things in place. Dr. Jonas puts me at ease and I have confidence in his knowledge of oncology.

October 2023

Dr. Jonas is respectful, kind, pleasant and best of all thorough in his decision-making for his patients. He sought advice and concurrence from several other specialists, colleagues and surgeons to select the most effective approaches for my diagnosis. He cares, and my family and I are truly grateful that God put us in front of him and the entire Piedmont Atlanta Cancer Team. His staff is amazingly helpful, courteous, and never seemed hurried when setting appointments, clarifying orders; and, did quick work of completing the necessary FMLA forms for my daughter's job so that she could be with me during chemo sessions/appointments. I thank God for Dr. Jonas!!

October 2023

Dr. Jonas and his ENTIRE staff are simply amazing. Courteous, professional, personable, and informative. My experience with these fine professionals has eliminated so much of my fear and angst associated with my sickness. I was fortunated to find Dr. Jonas.

October 2023

Always nice to be welcomed by friendly nurses and staff. Dr. Jonas and PA Scott are always so kind, answer all my questions, and bring me reassurance throughout my treatment. Thankful to be going to them.

September 2023

There is never a long waiting period. Everyone is always so pleasant and professional... from the time I check in when I arrive, to the time I check out when I leave. Dr. Jonas is the best. He always make me feel comfortable and answers any and all questions I have. I'm very pleased with him and his abilities.

August 2023

I can always count on him to take care of my current problems-he seems to listen then acts on what needs to be done if any! He is a wonderful and very delightful person and a GREAT physican! I am glad and thankful to be his patient!!

August 2023

I was referred to Dr.Jonas by nuerologist Dr.English at ANI and I have only met him once so far for my first appointment for about 2 minutes but He seems like a really nice doctor however his assistant Dr.Scott who handled my appointment that day was real patient and gave me much understanding on how my meds assisted in my healing process. I have a speech issue and he took time to listen to me even though it takes me quite a while sometimes to get out the things I want to say. I was really nervous that day because of bad experiences I'd had at previous places and Dr.Scott's professionalism and knowledge of my issue helped me to understand that everything would be alright. I'm sure that anybody that has an assistant this caring can only be the same. I look forward to my appointments with Dr. Jonas, he has an awesome team! Thank you

August 2023

Dr Jonas, as always, was thorough in his review of my case. He has been treating me for lymphoma since 2015 and I have no doubt that he saved my life. Thank you for being so caring and compassionate. You always make me feel at ease when I visit. No matter what I always leave with a smile. God bless you and your awesome staff.

August 2023

Dr. Jonas quickly senses my mood when entering the room. He always responds immediately and appropriately to ease any concerns I have about the state of my disease and how we are fighting it. Then he listens to how my life is going in general, with encouragement to help me keep my positive attitude. I trust him to be the doctor in charge of the attack. And the good friend to support me in my part of the fight. Thank you, Dr. Jonas!

August 2023

Of course finding out your mother has stage 4 cancer isn't easy, but after seeing several doctors and finding Dr. Jonas was nothing short from a blessing. Dr. Jonas is kind, caring, funny, patient, and very understanding! He takes his time to make sure he answers all your question, and that you fully understand. I can't stress how lucky we are to have Dr. Jonas by our side!!!

August 2023

He's a great doctor. He fit me in his schedule on short notice. He and his PA spent a good deal of time with my wife and I. Answered all of our question patiently. There is a reason his schedule is so full!!

August 2023

Dr. Jonas is brilliant, caring, and entertaining too. I appreciated his no-nonsense approach in discussing my case. I thought we were only meeting for an introduction, but he had already reviewed my test results and had developed a probable diagnosis. I could not be in better hands.

June 2023

Dr. Jonas and staff go out of their way to accommodate me, coming in from another state. I get fast, thorough test results back, and I have total confidence in him. Coming in all the way from Florida, says it all. He is the best. Shout out to Billy, as well.

June 2023

I have had nothing but great experiences with Dr Jonas and his colleagues. This year I was diagnosed with breast cancer for the second time and I was devastated by the diagnosis... Dr Jonas reassured me that he was going to do everything possible for me ( but you are not going to like me for it ) he quoted. My life has changed but I can't thank him enough for his help and support. Thank you Dr Jonas.
