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.

He has an excellent bed side manner, shows genuine care and concern for any questions, and takes the time to listen to what I have to say during the appointment. I have never had to wait more than a couple of minutes when I had an appointment with Dr. Koc (and most of the time, I don't have to wait at all). He is prompt and efficient. His job is not easy, but he maintains a calm, professional demeanor at every encounter (and he has a good sense of humor).
