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.

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.

It's too hard to schedule appts as clearly the providers are taking on too many patients. It takes months to get in to see a provider. Although Dr Zimmerman is an amazing doctor it is a bit discouraging to have to work around the clinics schedule.

Dr Zimmerman spent 45 mins of the appt reviewing medical records and not speaking to me, he didn't even know I was a terminal cancer patient before he started recommending long tests, my daughter had to advocate for my health care priorities because the doctor didn't understand who I was as a patient. He took up my time and my daughters time and didn't even care he did and was late to the appt and just a waste, how didn't he understand I was terminal or read anything in my chart before he saw me.

Every single time Dr. Zimmerman is late, and not just a little bit late. This time it was 45 minutes. I'm not sure why health care providers expect patients to not only be on time, but early, then they don't reciprocate the same. Obviously things happen, but if roles were reversed the patient would be forced to forfeit and reschedule.

He's obviously a qualified physician but not the most personable person on the planet.
