About

San Francisco Genetic counseling

San Francisco Genetic Counseling specializes in reproductive, prenatal and preconception genetic counseling. SFGC is supportive of those choosing out-of-hospital births and is sensitive to their unique needs.

SFGC also provides services for egg and sperm donor screening, as well as counseling for individuals with lingering questions after direct-to-consumer genetic testing, such as 23andMe and Sequencing.com.

SFGC is an LGBTQ+ and BIPOC ally. The goal is to support one’s whole, authentic self; to listen and understand as we inform about genetics, continually supporting in a holistic way.

San Francisco Genetics is owned and operated by Janine Gessner Mash, a licensed and certified genetic counselor based in San Francisco.
