Lauren Arroyo

Pond Lead

Lauren Arroyo began working at Sequoyah in the Backyard as Renee’s associate teacher in 1992. Renee hired her because she was an artist and believed this would be a strong support for the Backyard’s very creative and emergent curriculum. During the four years Lauren spent working with Renee, she discovered how much she enjoyed teaching art to kids so she pursued her BA at Pacific Oaks Teaching College in human development with a specialization in art education. After graduating, she moved into the position of Art Specialist where she saw the value of an integrated curriculum and it’s importance in offering children many different opportunities to learn through the creative voice found in art. Lauren realized the importance of providing a safe place for students to take risks and build confidence. After several years in the art specialist, she had truly fallen in love with the youngest students in the kindergarten/first grade. Here she saw the opportunity to provide a creative and exciting class while offering a fun, warm, safe, nurturing safe place for them. She felt her strength was in embracing the individuality of each student and encouraging them to discover their own strengths, and how to engage in learning from their own perspectives. So she took the next step and returned to Pacific Oaks to earn an MA in human development and to complete her education credential. Her thesis explored geo-ethnic storytelling with young students – an intercultural approach to diversity through personal family stories from the students and their families.

Erin Trefry

Visual Arts

Erin Trefry makes visceral, emotionally charged sculptural paintings. At an early age, she was awarded multiple scholarships that enabled her to study at the Maryland Institute, College of Art; Parsons, Paris; and The New York Studio Program (A.I.C.A.D.). Upon graduation, Trefry returned to teach at her alma-mater (LACHSA) where she received a series of grants to design and implement innovative arts curriculum. Professional designation along with her active role in education allowed her to maintain her autonomy as a working artist. As a descendant of textile designers, cobblers, and educators, her work suggests personal archeology. The warp and weft of fabric act as an inherent drawing and serves as a catalyst for her constructions. Shoes, handbags, shirts, belts, and pants once belonging to her mother are given new life in her sculptural assemblages. They echo the physicality of the body with “wounded symmetry.” Their association with Japanese armor, African masks, and the Commedia Dell’Arte attempts to evoke the depth of human behavior and to provoke a new lens into contemporary sculpture. Trefry exhibits, teaches under the guise of facilitating fearlessness, advocates for people who are experiencing homelessness, throws clay slabs, dances, and creates unusual spaces.
