Where Therapy Meets Humanity

Provia Psychology is more than a therapy practice—it’s a community rooted in connection, purpose, and a deep commitment to meaningful change.

Founded by Dr. Stacia Deiro, a licensed clinical psychologist, Provia Psychology began as a small, woman-owned business with a big vision: to offer accessible, affirming, and expert mental health care to the Southern California communities we love. From the beginning, Dr. Deiro’s heart has been focused on serving others and creating spaces where healing is possible for everyone.

We’ve grown quickly—from a handful of dedicated clinicians to a thriving group practice with offices in Long Beach and Newport Beach, and plans to continue expanding throughout Los Angeles, Orange County, and beyond. As we grow, our mission stays the same:

Our mission is to cultivate an environment of tailored support and continual education for our mental health clinicians and administrative staff, empowering them with the tools and expertise needed to deliver unparalleled care.

Through fostering emotionally safe spaces, we aim to provide an exceptional, transformative therapeutic experience for our diverse clients, showcasing comprehensive services and the expertise of our top-tier clinicians, ensuring a meaningful, inclusive, and impactful difference in their well-being.

We serve individuals across the lifespan—children, teens, adults, couples, and families—and specialize in a wide range of services including trauma recovery, neurodivergent-affirming care, anxiety and depression treatment, identity exploration, and psychological testing. We believe mental health care should reflect the richness and complexity of the people we serve, and we strive to offer personalized, client-centered care every step of the way.

Inclusion & Equity – We are proudly affirming of the LGBTQIA+ community, neurodivergent clients, and individuals from all racial, cultural, and spiritual backgrounds. We actively work to uplift voices from marginalized communities and create space for people to feel truly seen and respected.

Access & Advocacy – We understand that navigating the mental health system can be confusing and frustrating. That’s why we’re committed to removing barriers, whether through insurance guidance, flexible options, or simply meeting people where they are.

Excellence in Care – Our clinicians are deeply trained, trauma-informed, and continually developing their expertise. We provide ongoing education, supervision, and support to ensure our team is equipped to offer the highest quality of care in a deeply human, connected way.

Because we believe therapy should feel safe, transformative, and accessible.

Because we believe in showing up—for our clients, for our community, and for each other.

Because we believe mental health is a right, not a luxury.

Whether you’re starting therapy for the first time, returning after a break, or seeking a therapist who truly understands your lived experience—we’re here, and we’d be honored to walk alongside you.
