We post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.
I am a pathologist who specializes in head and neck and thyroid pathology. My practice is located in New York City. I help make a diagnosis for head and neck and thyroid cancer by examining cell and tissue samples using a microscope to detect the presence of cancer.
