When I arrived they took me right back. The provider came right in and we talked. I don't think I have ever been seen and completed that quickly and efficiently. Thank you for a great experience

Best medical appointment I've had in a while. Great doctor. Really listens. Looked at me and not computer screen when talking to me. Speaks In gentle voice, not commanding. Gave advice that made scientific sense, unlike some advice I've received from a couple of doctors lately. Did not talk down to me. Asked good questions. I will definitely recommend him, and return for more care from him.

Industry Relationships

University Hospitals is committed to transparency in our interactions with industry partners, such as pharmaceutical, biotech, or medical device companies. At UH, we disclose practitioner and their family members’ ownership and intellectual property rights that are or in the process of being commercialized. In addition, we disclose payments to employed practitioners of $5,000 or more from companies with which the practitioners interact as part of their professional activities. These practitioner-industry relationships assist in developing new drugs, devices and therapies and in providing medical education aimed at improving quality of care and enhancing clinical outcomes. At the same time, UH understands that these relationships may create a conflict of interest. In providing this information, UH desires to assist patients in talking with their practitioners about industry relationships and how those relationships may impact their medical care.

UH practitioners seek advance approval for certain new industry relationships. In addition, practitioners report their industry relationships and activities, as well as those of their immediate family members, to the UH Office of Outside Interests annually. We review these reports and implement management plans, as appropriate, to address conflicts of interest that may arise in connection with medical research, clinical care and purchasing decisions.

As of December 31, 2016, John Sullivan did not disclose any Outside Relationships with Industry.
