Testimonials from Dr. Jonas's Patients

April 2025

Dr Jonas is a ray of sunshine at a dark time. His confidence in my treatment, his ability to help me understand the ups and downs of my disease, and the thoroughness and professionalism of his staff has made this as good of an experience as I could ask for. Thank you!

April 2025

I've been a patient of Dr. Jonas for eleven years and I'm so thankful I was referred to him. He is a very knowledgeable, informative, thorough, kind, caring, and patient physician who has, and expresses, a lot of concern for his patients. Scheduling, and rescheduling appointments has been very good. His staff, that I've come in contact with, all have the same professional, cheerful, and kind attitude as he has. He has always come into the room with a cheerful and happy mood. I feel confident with the information he gives about my health; and the suggestions, instructions, recommendations, he gives me. There has never been a question or concern that I've had that he didn't take the time to answer; and always in a way that was easily understood. I've never regretted going to an appointment with him, and I know I can trust him to tell me the truth about any concerns or questions I have and about any health issues. He has always given excellent service and I would definitely recommend him to others.
