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.

Dr Collier is the ultimate caregiver. He is so knowledgeable, competent and compassionate. He has a delightful bedside manner and he is a very good listener. He advised me to have genetic testing which I have tried calling them twice now to schedule an appointment for counseling and the test kit. I waited on hold 38 minutes and was disconnected, held on hold another 18 minutes and left my name and number both times and have not received a call back. I do think they're having a problem with the genetic testing program which is unfortunate. I am most willing to participate in the genetic testing but can't seem to get hold of anyone. Outside of that I think CLEVELAND Clinic is a wonderful facility actually you're simply the best!
