Industry Relationships

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 1/24/2021, Dr. Greenfield 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.

Dr. Greenfield is excellent. He takes the time to explain why certain tests are done as well as the results. Cares about what he does. He is the ONLY MD at Cleveland Clinic that has personally called me to discuss test results. FYI--it is impossible to get established with a PCP at Cleveland Clinic! Please note that due to lack of availability to establish with a PCP, that deserves an F in rating terms.

Dr. Greenfield is a consummate professional; in every dimension. He is also a very rare and stunning role model for all practitioners in every niche of the medical profession. He has an innate sense of purpose, a well-honed drive to exhaustively assess circumstances, adroitly research immediate and less obvious solutions, and then astutely Implements a care plan appropriate to the situation. BUT, as or more Important to his hugely demonstrated technical competencies; he "listens" with great Intensity; absorbs and gages medical stats and data with alacrity; and exudes patient confidence borne of cultivated intellect, personal acumen, constantly-developing skill sets, and accrued wisdom: he's the 'complete package'.
