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 11/27/2018, Dr. Jang 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.

The office staff and doctor were excellent - really put me at ease and were so pleasant and friendly. They explained everything thoroughly. The only negative comment I have is that I did not receive my bowel prep instructions and so I had to call for them a few days before the procedure. received them promptly on my chart - and then in the mail a day AFTER the procedure.

The GI doctor strongly recommended I have the procedure done at the Cleveland Clinic. The soonest we could get an appointment was in 10 days. We live in Wyoming so going back home wasn't a good option. So, we took the time to visit family in Illinois, Indiana and Kentucky. We had a great time visiting family. - Dr Jang was very personable and friendly. I trusted Dr Jang's abilities because the GI doctor had faith in him. I now trust Doctor Jang because I no longer have the pain I had before the procedure. - I really trust the Cleveland Clinic and have scheduled another appointment to see a vascular doctor there. Thank you for helping me!
