Who We Are
Clinican-Owned ABA agency in California
Our Mission
Located in the East Bay Area of California, SoPo is a small, clinician-owned and operated ABA practice with a deep commitment to community. As a women-owned and minority-owned business, SoPo is uniquely positioned to understand and address the needs of underserved populations—particularly families navigating systemic barriers related to language, culture, and access to care.
At SoPo, we believe that quality ABA services must go beyond clinical expertise—they must be personal, respectful, and inclusive. Our approach is grounded in evidence-based practices, cultural humility, and a strong belief in partnership with families. We design individualized, affirming treatment plans that reflect the unique strengths, values, and goals of each client.
Our mission is clear: to expand access to innovative, compassionate behavioral therapy that empowers families, celebrates neurodiversity, and fosters long-term growth. With every session, we strive to make families feel not just supported—but truly seen, heard, and valued.
