About Hillside Horizon
Hillside Horizon is a Joint Commission accredited, California licensed residential treatment center in Canyon Lake, California, serving adolescents ages 12 to 17. This boutique, family-owned program provides residential care for teens facing mental health and behavioral challenges alongside any co-occurring substance use.
A Small, Home-Like Program in a Lakeside Setting
Hillside Horizon keeps its census intentionally small, with gender-specific homes in a lakeside setting that includes mountain views and outdoor activities. The environment is designed to feel like a home rather than a clinic, so teens in Canyon Lake and across the region can focus on stabilization and skill-building.
Blending Clinical and Experiential Therapy
Care combines evidence-based clinical work with experiential and holistic therapy, including art, music, yoga, and adventure activities. Treatment plans are individualized for each teen and involve the family in the process.
Hillside Horizon works with most PPO plans and some HMO plans, and offers self-pay and sliding scale options. Reach the center to check availability and confirm coverage.
