Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. 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.

I literally cannot say enough great things about Dr. Kessler. He is my hero!

Reviewed on Feb 9, 2021

very comfortable and was well informed and I felt like he's the right doctor for me .

Reviewed on Jan 15, 2021

I saw Dr. Kessler in the hallway before my surgery. I know I see him in the operating room as well but this meeting in the hallway really made me feel good about my surgery. It was just that personal interaction. Dr. Kessler is great 10/10 definitely recommend.

The fellow that worked with *Dr. Kessler was wonderful. He helped me relax and validated my anxiety and fears.

*Dr. Kessler went above and beyond to coordinate care with other doctors while I was in state.

Reviewed on Oct 30, 2020

My Stoma nurse made a great impression on my husband and myself, if it wasn't for her (mainly) and Dr. Kessler's Resident I would have left the Cleveland Clinic with the same answers I had gotten from the hospital's ER, multiple Doctor's appointments and the specialist's who referred me and I'd be ok with that if he had talked to me not over me. He admitted he didn't read the information about my medical history I brought in or records yet and wasn't open to a dialogue when I would ask questions. as I said the Stoma nurse is Amazing at her job and his resident needs be heard because he doesn't let him offer him the chance in the room while he's there.but both stated that if you need a colostomy done that Dr. Kessler is the Best...

Dr. Kessler and his Fellow were both very caring and considerate.

Reviewed on Sep 29, 2020

Dr. Kessler is very professional, and does not sugar coat or "dumb down" any information. Although it would be difficult for a person without medical training to understand some of his terminology, but I really appreciated that he gave me straight information and answered any questions that I had.

Reviewed on Sep 8, 2020

Dr. Kessler is the best. He is a caring, kind provider who always takes into account my ideas and concerns. He offers appropriate options for my care, and regards his patients as people first (balanced with high quality medical care).

Excellent practitioner! A professional, caring physician in every aspect.

Shirley was excellent. She returned messages and made sure that she kept me in the loop as to all my files getting to the doctors, as I requested.

Reviewed on Jun 26, 2020

Dr. Kessler is clearly as very smart person. My one concern is that I did have some questions after thinking about what he said that I wish I had thought of at the time. Also, I feel like I am not sure what exactly his plan of action, if any, is. I know he does not want to do surgery right now, and because of the steroids, he cannot do it right now. However, I do hope that after my tests next week, we will have more options, including surgical if necessary, to try and help alleviate the constant pain. If not, then I hope he is willing to help me find a way to manage the pain in a more effective way. Or whether he feels there may be other things I could do to alleviate the pain.

Reviewed on Jun 26, 2020

The one thing I had a problem with is that they changed which surgeon was going to assess me two days before I was to be seen. I was originally scheduled with Dr. Dionigi: however, she was apparently leaving the Cleveland Clinic and felt I should see someone else. I feel that it was foolish to schedule me with someone who was going to leave. I wish you had thought this through better...that way, I might have had an easier time getting all the scans, etc. to Dr. Kessler before my appointment.

Reviewed on May 1, 2020

Dr Kessler and team were very thorough and answered all my questions I had

Reviewed on Mar 6, 2020

Dr. Kessler's was very thorough. He explained all aspects of the exam and upcoming procedures in a very caring and professional manner.
