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.

Meet the Owner
Tiffany Tuong Vi Nguyen
– Owner & Board Certified Behavior Analyst (BCBA)
Serving families in the east bay
IN-Home ABA Therapy & Telehealth Services
San Leandro, Ca
As a Board Certified Behavior Analyst (BCBA) and the owner of SoPo Behavior, Tiffany has built her practice around one simple belief: every child deserves expert, compassionate care — and every family deserves a provider who truly listens.
SoPo Behavior is a boutique ABA therapy practice serving children, teens, and young adults throughout the East Bay Area of California. What sets SoPo Behavior apart is Tiffany’s hands-on approach — she serves as both the owner and primary clinical supervisor of direct ABA services to prioritize clinical quality assurance, meaning your family works directly with an experienced BCBA from day one through every milestone along the way.
With over a decade of clinical experience in Applied Behavior Analysis, Tiffany brings a rare combination of expertise and genuine heart to every family she works with. She holds a Master of Science in Psychology with a specialization in Applied Behavior Analysis from Capella University and earned her BACB certification in 2021. Her clinical focus centers on incidental teaching, naturalistic teaching, and early intervention strategies — approaches that help children build essential life skills in the real-world moments that matter most, from home routines to social settings and beyond.
At SoPo Behavior, no two treatment plans look alike. Every program is thoughtfully individualized, grounded in evidence-based practice, and designed not just to support your child’s progress — but to empower you as a parent with the tools and confidence to carry that progress forward.
Tiffany is also a multilingual provider, fluent in English, Cantonese, and Vietnamese. She is deeply committed to serving families from diverse cultural and linguistic backgrounds, including minority and immigrant communities who too often face language barriers when trying to access quality behavioral health services. At SoPo Behavior, inclusive and culturally responsive care isn’t an afterthought — it’s at the core of everything Tiffany does.
Whether your family is just beginning to explore ABA therapy or looking for more personalized, expert support, Tiffany is here to walk alongside you — every step of the way.
