Deundra Hundon

She served for over 10 years at San Francisco University High School as Director of Outreach for the Summerbridge Program. Deundra recently fulfilled a dream of hers by becoming a birth doula, and was delighted to be able to support her daughter through pregnancy and labor at the Birth Center in this capacity. Deundra has a deep love for families and advocating for fair and equal education opportunities, and enjoys connecting with people across diverse communities.
