I came to Dr. Jonas for a second opinion. I have stage 3 colon cancer, and I wanted his recommendation for post op treatment. I found him to be very approachable, and easy to understand. He impressed me as genuinely caring, vastly experienced, and very professional. He quickly established trust, and if I was located near his office, he would be my first choice for treatment. I also found his staff to be helpful and knowledgeable.
