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 specialize in adult primary brain tumors, including glioblastomas, anaplastic gliomas, low-grade gliomas, meningiomas, and ependymomas as well as metastases to the nervous system from cancers outside the brain. I am particularly interested in primary central nervous system lymphoma (PCNSL) and am currently conducting basic research to uncover genetic abnormalities in PCNSL to better understand and treat this disease.
