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.
As of 1/23/2018, Dr. Koc has reported no financial relationship with industry that is applicable to this listing. In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients. Interactions with industry are essential to bringing the researchers' discoveries to the public, but can present the potential for conflicts of interest related to their research activities. Click here to view a listing of instances where Cleveland Clinic has identified a Public Health Service (PHS)-Reportable Financial Conflict of Interest and has put measures in place to ensure that, to the extent possible, the design, conduct and reporting of the research is free from bias.

Doctor Koc is a pleasure. He knows his stuff (I'm in remission) and does a thorough job every visit. When I tell him something is not right, he listens and sometimes orders a test to follow-up. I have great confidence in his ability and enjoy our conversations. He is GOOD! Also, Shelley and Rita in reception are excellent - pleasant, friendly. Like these people!

Dr Koc always is prompt. I suspect he comes in early and does his homework to make all his appointments on time. From all my years, this is the only doctor who does not keep me waiting long in an exam room. That's wonderful.

I am so pleased with the care at the Cleveland Clinic. Dr. Koc has been so attentive to my care. He encouraged me to seek a second opinion within the dept so that I could make a decision I was most comfortable with regarding chemo!! who does that! He ALWAYS makes sure he answers any questions I have and makes sure I understand his answers. I have the utmost faith in him and have recommended him to others.

As a patient if Dr Koc's since 2010, he has never kept me waiting for an appointment and actually has come to the waiting room to bring me back when his other team members were busy. He is always respectful, honest, and approachable. He shows concern for me as a patient and I never feel rushed during a visit.
