As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

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.

After seeing three doctors (who left their practice in the Cleveland Clinic Functional Medicine and my primary gastroenterologist before them), Dr. Achkar is a blessing. All the above are very true of Dr. Achkar. Only one of the Function Medicine doctors would have scored around a 4. The other two not even a 1.

No video staff was required. I have a lot of hope that Dr. Achkar will help me feel better soon. This has been a long tiring road for me and my family. He is very patient, kind, and understanding and listens to me. I appreciate that and hope to feel better. He certainly is an asset to your hospital.

Reviewed on Sep 27, 2023

Dr. Achkar listened very patiently while I explained my acute symptoms and recent hospitalization. He repeated the most important details back to me to confirm his understanding and reviewed his direction about my plan of care a second time before ending our appointment. That is an indication of an excellent physician! I became Dr. Achkar's patient because the GI that had been my doctor for 20 years retired. While I was very reluctant to change to a new doctor, Dr. Achkar was VERY highly recommended to me. He is everything and more that I was told about him. I would not hesitate to recommend him to anyone facing the challenges of IBD. He is a gem!!

I had an in-person visit that I thought was virtual. When I realized my error, I desperately tried calling Dr. Achkar's staff. I spent 15 minutes going through the phone tree/on hold, before being connected to someone who promptly hung up on me. I called back, and had to repeat the phone tree/on hold. Eventually - after the start of my appointment - I was connected to someone in Dr. Achkar's office, who rescheduled my appointment. She then told Dr. Achkar about my dilemma, and he graciously agreed to see me virtually that day.

Reviewed on Aug 28, 2023

Dr. Achkar is fantastic! He accomodated his schedule to meet with me virtually after I screwed up. The problem is Cleveland Clinic's crazy system in trying to reach an individual provider/practice.
