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 11/25/2016, Dr. Mulligan 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.

Dr. Mulligan is an excellent, caring doctor. My condition is complicated and, unlike certain other CCF physicians I have visited over the past several years, he is open-minded, patient and willing to look into new methods of treatment. Dr. Mulligan treats me with respect and sincerely tries to understand my medical issues and concerns. He is everything a physician should be.

As stated earlier, I feel that the Dr. did not include me in the decisions made (or the lab, either) as the Dr. knew that the blood tests requested were from the past. About my on-going medication (Synthyroid) he did give me knowledgeable info and consulted with me. The test he requested for the bone density test was right on.

Dr. Mulligan made me feel at ease, answered all my questions, didn't immediately jump into a therapy plan (wants to be positive of where pain is coming from before doing so), did not seem rushed at all to move on to the next patient, and seemed very knowledgeable and confident in his abilities. I look forward to being under his care, and would highly recommend him.
