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 11/7/2017, Dr. Bergman 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.

It has typically been difficult to make appointments--generally need to do so well in advance. A new format with physicians assistants may change that. I do seem to get more frequent notices of availability now.

When he got in the dr. apologized and explained that he had a patient with a complicated medical problem.

Waited over an hour to see the doctor. Timely appointments not available even when having ongoing issues which need more immediate attention. Not enough Functional doctors available!!!

Virtually no waiting and Dr. Bergman spent a lot of time with me.

Reviewed on Mar 26, 2018

While I did wait in the exam room, I did not mind since Dr. Bergman took such care and time with me when I started at Functional Medicine. I believe that my first appt. most likely a patient had to wait while he took such care with me, so I did not mind at all since that initial intake is so very vital to getting information correct the first time since it is the cornerstone of future care.

Dr.Bergman was very courteous. he did not rush. He did included me in the decision making

I love Dr. Bergman. Not only has he helped me to get off of a medication for a chronic condition, but he is helping me prevent another condition. He always explains everything completely, and he is so respectful of my veganism when recommending supplements. He researches which supplements are the best for me and provides research results and his opinions on everything we think about trying. I've never felt better!

Dr. Bergman spent over an hour with me listening, asking questions and explaining the protocol that he was recommending.

Dr. Bergman is very nice and genuinely concerned.

Reviewed on Aug 2, 2017

Dr. Bergman always engages in dialogue regarding treatment recommendations and encourages me to make decisions based on information he shares. Mine has been an interesting journey of "peeling the onion" and he intuitively knows where to go next. He's the best doctor I've ever had (and I'm 49)!

The best care anywhere. That is why I drive 6 hours. Don't know what I would have done without Dr. Bergman and Functional Medicine.

Wish I had had more time to ask questions.

Reviewed on Jun 21, 2017

This is the best physician I've ever had. He takes on my health challenges as a personal quest, is so personable and professional. He is very knowledgeable and yet open to my suggestions from my personal study of my condition. I feel respected and welcomed when I meet with him. I never feel rushed when meeting with him. I feel I can trust his recommendations, which is very important to me.

Reviewed on Jun 8, 2017

Dr. Bergman went over everything and gave us very detailed instructions, every one that we dealt with explained everything in detail to make sure we understood

Reviewed on Jun 8, 2017

Dr. Bergman is very thorough with his explanations and instructions. He will explain things to me multiple times and in multiple ways when necessary. He always checks in with me to be sure that I'm comfortable with the treatment plans he maps out for me. If I'm unclear about medications or follow-ups, he/his office promptly responds to my MyChart messages.
