To advance the future of mental health care through innovative, evidence-based treatments—delivering excellence, fostering human connection, and offering unwavering compassion that empowers every individual to thrive.
Alter Behavioral Health was born from a bold idea: What if we built a mental health system not just around treatment—but around people?
When Michael Castanon founded Alter Behavioral Health in 2019, he envisioned more than just a treatment center. He saw the need for a deeply intentional, person-centered model that treated clients with the dignity, care, and precision they deserve. After years in both finance and behavioral health, Michael recognized that meaningful outcomes come not just from protocols, but from the people delivering them—and the heart behind every decision.
That vision—to deliver care that is both clinically excellent and emotionally resonant—led to the creation of Care Predictor, a platform born from the need to excel and perfect workforce development, elevate treatment outcomes, and ensure deep, authentic connection between caregivers and clients. From pre-hire to post-care, Care Predictor empowers organizations to align people, purpose, and performance—all in service of the therapeutic alliance that lies at the heart of healing.
At Alter, this commitment is lived daily. Every team member is carefully selected not only for their credentials, but for their capacity to connect, uplift, and support the healing process. By investing in people first, Alter Behavioral Health is not only transforming lives—we’re redefining what it means to lead in behavioral healthcare.
Today, Alter Behavioral Health stands as a gold standard—a sanctuary for healing, a system built on trust, and a future-forward approach that puts people first, so that every client feels empowered to heal, transform, and thrive.
