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 8/4/2017, Dr. Estemalik 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.

I always feel very rushed with Dr Estemalik, but he is the only neuro at the Avon location. This was my first botox injections appointment, so if they work, then the benefits outweigh the rushed feeling I get. I just feel like I always leave and have questions I forgot to ask. I also noticed not all the types of migraines I get were listed in the paperwork I later received. I googled this doctor and noticed similar comments. Perhaps his patient load is too heavy and there is a need for more than one neuro in Avon? Thanks.

My checkout and booking of the next botox appt took longer than my actual injection appointment. That doesn't usually take so long.

Dr Estamalik was who I was scheduled to see but I spent most of my visit with Dr Donnelly. I enjoyed talking with Dr Donnelly and she listened. when Dr Estamalik came in he didn't really want to listen to what I had to say and blew off my concerns.

The doctor prescibed me a medication for migranes ive already tried, half the reason I went to him was to get an alternative option. He should have seen ive already been given that medicine on my chart. Unfortunatly I failed to realize it was the same medicine because he used a differnt name for it. However he did think to ask for a bloodtest to check my thyroid which came back to show problems. So while Im mad he failed to notice ive already tried the meds he did find the problem with my thyroid which im thankful for.

Very professional, caring, knowledgeable, spoke on terms we could understand, showed patience with us and answered all of our questions, made us feel at ease with the upcoming procedure and during the procedure. Very supportive and upbeat. Highly recommend him to another person who may need care. Top notch doctor. One of the best I have seen in my lifetime, and a great representative of Cleveland Clinic.

He was fantastic. He knew so much about my medical conditions and history, and seemed so genuine in his concern for my health. He seemed like the type of provider who would advocate passionately for what is best for his patients.

Dr. Estamalik provided thorough information throughout my exam and explained how we will fix the problem.
