Dr. Ammori is the best doctor I could have been recommended to. I am very impressed with him and his staff. He explained there was a medical emergency that day, that is why I had to wait a little longer to be seen. I could not ask for a more caring doctor to be sent to. Thank you!

I was very impressed with Dr. Ammori. He did an excellent job. He seemed very knowledgeable about my condition. He listened attentively to my comments and was very informative in his explanations.The end result of the office visit was that surgery for me is not possible, so I do not need to have Dr. Ammori any further. However. . . I was so impressed with Dr. Ammori that I wish he could be my permanant doctor. What a great person he is!

I am in awe of Dr.Ammori *** His quiet confidence my first appointment allowed me to feel confident in my switch of teams from another provider. During pre- op he came to see how i was doing and review the process. He was a voice of calm and reason. The surgery was major and he and his residents were rock stars!!! Everything went better than expected. I owe a lot to Dr. Ammori. UH is lucky to have 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.
