Tamara-001 Tamara Hernandez – Executive Director

Tamara Hernandez’s passion for children’s education began ten years ago when she gave birth to her first child, Tuesday.  Tamara saw that her daughter was an eager learner and so began looking into the latest research in childhood development to meet her needs. Tamara became fascinated with the amazing potential children have to learn anything at a young age, and especially their ability to learn multiple languages at the same time.  Eventually, this led Tamara to co-found an educational production company, Productive Playhouse, geared towards piloting and creating content teaching children foreign language, reading, math and music in ways that challenged them but were fun and engaging at all times.  One of the production company’s first projects was to create curriculum and teach a trilingual foreign language class at Kidspace Museum in Pasadena. Tamara then went onto to co-produce, direct and write several educational series, including Your Child Can Learn, and Your Child Can Discover.  These series won nine parenting awards between them, including the Parenting Media Winner, The National Parenting Center Award and the Brain Child Award Winner.  The series sold in many languages all over the world, which eventually helped to launch Oasis Trilingual Community School.  As Tamara’s two children grew, she became a volunteer parent for the Pasadena Unified School District.  Here she expanded her experience with educational organization by becoming a School Site Council member, helping launch and manage the STEAM program for the Mandarin Immersion program, starting the after-school book club, coordinating the implementation of after-school Spanish classes, and co-launching a Mandarin Immersion Pre-K.  Before founding Oasis, Tamara received a B.A. in English Literature from UCLA, and became a screenwriter and director after college.  Her first two short films premiered at the Sundance Film Festival, with one then playing at the Cannes Festival and in theaters throughout Paris, eventually selling around the world.  Her first feature film won Best Narrative Feature at the South by Southwest Film Festival, and awards at five other festivals.  After her first feature, Tamara turned her focus to documentary filmmaking, and directed two films, including The Chicano Collection, about the Chicano art movement, for executive producer/art collector Cheech Marin.  The Chicano Collection is now used to teach students about Chicano art movement during Latino History Month throughout schools in the United States, and her short film is currently used as an example to teach graduate students short filmmaking at USC.  Tamara is extremely grateful and thrilled to work alongside such an amazing and talented staff at Oasis, and is proud to witness everyday the behind the scenes hard work, dedication and thoughtfulness the staff puts into the lives of their students each and every day!
