Testimonials from Dr. Jonas's Patients


Dr. Jonas was great. I went in for what I thought was a minor issue, but I'm glad I addressed it with him. Dr. Jonas was really personable, answered all my questions and seemed very knowledgeable.


Dr Jonas and his staff genuinely care about you! He is straightforward, caring and very knowledgeable. I trust him completely with my medical needs. Thank you Sir!


His humor and honesty are much appreciated. I look forward to seeing him.


I would highly recommend Dr Jonas as he is not only very knowledgeable, and thorough, Dr Jonas is also an excellent partner as he is willing to communicate with other doctor's when it's needed / appropriate. He is also very caring as I had swelling around the inside of my knee but I have autoimmune swelling and it wasn't the reason I was there, and he ordered an ultrasound that confirmed multiple acute DVT Blood Clots and likely saved my life.


Dr Jonas, Scott, and the staff they work with are quick to respond to any questions I may have. Friendly, on time, and knowledgeable. They help make my visit fun!
