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.

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.

The fellow spent the majority of the time explaining and discussing my conditions and outside records. He also did an excellent physical exam. Dr. Collier seemed to be in a hurry and nervous during my visit. I was not comfortable with him and concerned that his recommendation of doing coronary angiography with wire pressure measurements by another Cleveland Clinic cardiologist was too aggressive and may be unnecessary. While he answered my questions, I was not confident in his physical exam which was cursory at best, and only done after I requested it. He had me stop breathing while he listened with a stethoscope to my right chest and said " Your valves are normal".
