Testimonials from Dr. Jonas's Patients

June 2024

Dr. Jonas and NP Kolbas are an amazing duo. Their bedside manner was outstanding, they both listen, ask questions, answer questions and are fully engaged with the patient. I never got a sense that they felt like they could be doing something else and I greatly appreciate their thorough care. I could tell that my history and labs were reviewed before either walked into the room. Thank you to both for being amazing providers as I was losing hope in the healthcare system.

June 2024

I am not a person who has faith in the medical establishment. However it is a doctor like Dr Jonas, that shows the world why people why doctors can be magical people. Dr Jonas approache is straightforward, humorous, and if you do what he tells you to do, which I'm rarely prone to do, you'll get better. I never anticipated having a good experience while dealing with stage 4 cancer, but Dr Jonas's motivated me, guided me, and put us on the path to absolutely crushing and killing the cancer that I have. That said, my recovery is seemingly going very very well. I have Dr Jonas and his awesome staff to thank for it. Every single one of them is not only enjoyable, they're fun to be around. And that is no small thing when you're dealing with cancer. Simply amazing people in Dr Jonas's practice entirely. If you get the bad C word, you will not find a better doctor.

June 2024

Dr. Jonas is amazing. He mixes a keen sense of humor with outstanding oncological skills. After shrinking my tumors with chemo, he spearheaded my surgeries, coordinating closely with the best surgeons in Ga. to get me the help I needed. Simply the best doctor I have met in all my years.

May 2024

Since my primary care physician referred me to Dr. Jonas, I have never had a bad experience in his office. He is very sweet, communicative, funny, and thorough during my appointments. My appointment was very quick and efficient. I was in and out in about an hour no more than an hour and half. I always enjoy my visits with him and come back and refer my friends and family to him. If I could rate him a 10/10, I would :).

Dr. Jonas is a great listener and caring doctor. I would highly recommend him. He will sit and listen and if he senses you don't understand or have more questions he'll say "I feel like you have more concerns let's talk about them." Amazing!

My visits with DrJonas are always informative and his ability to make you feel at ease is reassuring even though we are dealing with cancer issues.
