The doctors examination was terrible, he pressed so hard on the tail bone while examining rectally, I was really in severe pain for a week since that day, he really tortured me, besides, he had a junior Dr with him who Examined same way right after without getting my permission , I am not a field experiment for them to practice on me, without my consent,it was really a terrible experience, also. Dr kessler's findings were all wrong and against all Dr's findings that I saw so far, he should not be practicing medical.

I will never recommend Dr Kessler to anybody, he is too aggressive, harmful and without knowledge on how to Exam, he made me suffer of pain with tears during Exam and for the a week after Exam including back pain after he pressed very hard on the tail bone, and allowing the PA doing something without my consent, I was not a field experiment to nobody, they had me laid on my side which I didn't see what was going on behind me,btill after the fact, THAT WAS RIDICULOUS, DISGUSTING, UNPROFESSIONAL, his findings were wrong and against all other Dr's findings that I ever saw,

I was hugely impressed by Dr. Kessler and his team. Dr. Kessler made me feel relaxed and comfortable, answered my questions thoughtfully and provided his recommendation clearly. The team took extra time and extended my appointment to do an unscheduled scope, even though it was late on a beautiful summer Friday afternoon. I will feel confident having Dr. Kessler preform my surgery.
