Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

Dr. Kessler was very warm and friendly, and has always shown great respect for my concerns, as well as those of my wife, who accompanies me on these visits. He is very attentive to both of us, and was obviously making an effort to make us comfortable, as well as to be "seen and heard." He is a very good doctor, but also a very good person.

Reviewed on Sep 22, 2023

I loved Dr. Kessler . He spent an hour and a half with me, explaining my surgery, what he was going to remove, my recovery time and how long I would spend In the hospital. He was very soft spoken and has a wonderful bedside manner. He made me like I was Important and In good hands. He spent time getting to know me which Is more than I got from the surgeon at CAMC. He spent all of 15 minutes with me. I felt like a weight had been lifted off my shoulders when I left. I have never had any type of surgery before and was very apprehensive .

Dr. Kessler is an amazing Dr. He truly cares for his patients and I am so thankful for what he has done for me. His staff is also great as well.

Reviewed on Aug 22, 2023

The Fello was very pleasant and kind, however; Dr. Kessler was extremely unpleasant and could certainly have been more kind than to tell me he ccx would not do surgery and I would die. I obviously knew that as I was seeking a second opinion from a higher tierterary facility. I certainly expected more or at least kindness.

Reviewed on Aug 1, 2023

I really appreciate how quickly I got a response on the patient portal when I had questions following my appointment. Dr. Kessler was very patient and prepared to give me as much time as I needed during the appointment for questions. He made me feel comfortable, important and validated, I really feel like I am in the best hands.

Dr Kessler was very kind and explained what I needed to do. His resident or whatever she was lacked in patient concern. She needs to work on her communication skills.
