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 12/20/2017, Dr. McCullough 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. McCullough listens thoroughly. Same with explaining and answering questions. Can we clone him? He's THAT good!

This was my first meeting/visit with Dr. McCullough. I was very pleased with his knowledge, care, and particular insight into my diagnosis--NASH. I feel like I made a wonderful choice in asking for the appointment with him in particular.

I have great respect for Dr. McCullough. I've never had the kind of care Dr. McCullough provides me. My wife and I feel relaxed and in good hands when he's in the room. He's direct and to the point, and will listen and address every question my wife or I have. I have complete trust with Dr. McCullough and his staff, and I feel very lucky to have chose him for my care. I don't know where I'd be right now without Dr. McCullough's care.

Dr. McCullough is a wonderful representation of the Cleveland Clinic. Heis more than knowledgeable and very interested in my care and comfort dealing with a serious illness. He goes out of his way to answer my concerns. This is why we chose this facility even though we must fly there.

Dr. McCullough was wonderful. Spent equal time listening as he did talking. He was personable and had a very approachable and pleasant demeanor. I think he should teach classes to other doctors :) I can sign my brother in law up! Wish he had a clone that would like to be my primary care physician.
