Industry Relationships

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 10/19/2021, Dr. Sullivan 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.

I absolutely LOVED Dr Sullivan. When it comes to the point of needing multidisciplinary care it's normally been a long journey to get to this point. So you are more complex and the journey has been long. So finding someone like Dr. Sullivan to listen and show care and concern was a welcome relief!

We primarily discussed my symptoms and findings of previous physicians to determine which specialists to see at The Cleveland Clinic. I was not expecting a diagnosis or treatment options from this initial visit. I was quite satisfied with the choices Dr. Sullivan made, with my input, as a roadmap forward for my care.

I do not have any issues with Dr. Sullivan he's been awesome. Especially since Dr. Ha never followed my case after our first meeting. I am having difficulties with Dr. Li from neurology. I can not say a bad word about Dr. Sullivan. I call him, Dr. Litchin and Dr. MacDonald my 3 Cleveland Clinic angels.

The "Good" ranking is only because of the uncertainty with Long Haul Covid. There so many unique traits that seem to accompany the Covid experience, with some of them not be able to be Identied. I am extremely pleased with Dr. Sullivan and his expertise.
