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 11/10/2021, Dr. Griebeler 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.

Dr. Griebeler always listens to me and takes into consideration my preferences as a patient when making decisions about what is best for my health. I am always very pleased with his care!

Dr Griebeler and the resident with him (I think she was a resident, cannot remember her name) were incredibly thorough and personable. He broke everything down so it was easy to understand, included me in decisions and thoroughly listened to my concerns. It's been a long time since I've been optimistic about the direction of my care and I'm so glad to have the opportunity to have Dr. Griebeler on my team.

I was hoping to change my appointment date and although I couldn't find anything online, Dr. Griebler himself responded to my My Chart Message and had his staff reschedule me for the date I was looking for. Very much appreciated!

Dr. Griebeler is a wonderful physician who always takes the time to listen to my questions and concerns. He is encouraging and supportive about my problem and has never made me feel embarrassed about my weight issue.

Up until this appointment, my appointments were virtual. This visit was at the Cleveland Clinic's main campus. It was a pleasure to meet with Dr.Greiblier in person. He is personable, answered mY questions, and provided me excellent guidance for my care.

Reviewed on Oct 28, 2021

Due to poor communication and misinformation I was without one of my necessary medications for a little over two weeks. Dr. Griebler was not concerned with this and his specific office did not tell me I needed to make an appointment in order to get more medication prescribed. The resident who was assisting him was very nice but she only knew so much of the situation. As a doctor I've been seeing for multiple years I was disappointed with my experience with Dr. Griebler.

I believe very strongly in the good work and care that Dr Griebeler, his department and staff provide. He and his residents listen intently to me and have always provided me with the perfect next step in my healthcare plan. With his guidance and support over the last eight months, I've been able to change my lifestyle and lose over 50lbs. He's quick to point out that it's through my own work but I beg to differ and I recognize he and his team have changed my future!
