Diana Arbas teaches 11th grade American Literature at Port of Los Angeles High School in San Pedro, CA.

Her students use literary and nonfiction texts to explore the impact of race, class, gender, and more on equity and agency in America.

She lives in San Pedro and enjoys coaxing blooms out of her houseplants and wandering through museums by herself. Diana has a Creative Writing B.A. and Journalism minor from Mills College.
