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 12/31/2020, Dr. Zhou 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.

I can't say enough about Dr. Zhou. I had imposed on her with a couple inch high pile of records, summaries and CDs. She reviewed them all at least a couple of times before we met. She had a preliminary plan before our face to face. When we had our first visit, she knew everything I had sent her and tried to communicate in writing. We had an extremely fruitful, productive and enlightening conversation. My condition causes extreme fatique and brain fog so it is more difficult to converse and transmit information. Dr. Zhoe had it spot on, she answered all my questions, offered a lot more information and had a plan of attack going forward. I was so relieved we had a meeting of the minds and I felt confident we were going to get somewhere after 20 years of not being diagnosed. I can never thank her enough.
