Bita Nehoray, M.S., L.C.G.C., is a licensed board-certified genetic counselor specializing in cancer genetics. She has a master’s degree in human genetics and genetic counseling from Stanford University and a bachelor’s degree in integrative biology from University of California Berkeley.

She is fluent in Spanish and Farsi, and is committed to advancing the provision of cancer genetics services to medically underserved and culturally diverse populations.

Nehoray joined the City of Hope Division of Clinical Cancer Genomics in 2012. Her clinical responsibilities include providing pro-bono cancer genetic counseling services to underserved Latino families through an outreach program established by the Division of Clinical Cancer Genomics, and supported through government and foundations grants and compassionate funding, as well as providing genetic counseling services for City of Hope’s pediatric population.

She is a member of the National Society of Genetic Counselors, the Collaborative Group of the Americas on Inherited Colorectal Cancer and the American Society of Human Genetics.
