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.

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.

Reviewed on Apr 4, 2024

I traveled almost six hours to get to see a doctor here. I feel the visit with the doctor was very short and not informative at all. She told me I few things I had and could have. She didn't tell me how to treat or deal with any of the issues while at the appointment. I had to send multiple messages about my concerns and she responded very vague. I had to ask additional questions and got a response about medications she would prescribe. Still very vague and not sure what for sure the medication does and how to deal with the other issues she said I had as charted on my records.

Reviewed on Sep 12, 2023

Dr Olansky was straightforward and thorough. She listened to me and did not question the severity or validity of my complaints. Unfortunately, my issues didn't seem to be in her department.One of the tests she ordered was not correctly entered into the system but I understand that mistakes happen and it's one click between a given test on serum vs CSF and it's not hard to select the wrong one. I only discovered this later.

Reviewed on Sep 12, 2023

I don't know that my ratings are a fair reflection of Dr Orlansky or the endocrinology department. I think if my issue were endocrinological in nature, they would be more successful in addressing it!I was very impressed by Dr's knowledge of neuroendocrine and other functional tumors. These are pretty rare beasts and she knew exactly what tests to order to make sure I didn't have any. While I certainly wouldn't like to have them, it would have been an answer of sorts--but it doesn't seem to be the case.
