About INNH Addiction Treatment
Two decades of compassionate, evidence-based addiction treatment in the heart of Long Beach, California. Discover our story, our mission, and the team that makes recovery possible.
Our Story
INNH Addiction Treatment was founded in 2006 by a group of addiction medicine physicians and recovery advocates who saw a critical need for high-quality, personalized treatment in the Long Beach area. What began as a small residential program with just 12 beds has grown over the past 20 years into a comprehensive 39-bed facility offering the full continuum of addiction care.
Our founders believed that lasting recovery requires more than clinical intervention alone — it demands a healing environment, genuine human connection, and unwavering support. That philosophy has guided every decision we have made, from the design of our campus to the therapists we hire and the programs we develop.
Today, having served more than 6,200 patients, INNH Addiction Treatment stands as one of Southern California's most respected addiction treatment centers. Our 83-member team carries forward the founders' vision every day, treating each patient with the dignity, respect, and individualized attention they deserve.
Our Mission
Our mission is to provide compassionate, evidence-based addiction treatment that empowers individuals to achieve lasting recovery and reclaim fulfilling lives. We are committed to treating the whole person — mind, body, and spirit — within a supportive, judgment-free environment at our Long Beach facility.
We believe that every person deserves access to exceptional care, regardless of background or circumstance. Through clinical excellence, innovation, and unwavering dedication, we strive to be the most trusted name in addiction treatment across Southern California.
Treatment Philosophy
At INNH Addiction Treatment, we view addiction as a complex medical condition that requires individualized, multi-dimensional care. Our treatment philosophy integrates proven clinical methodologies — including cognitive behavioral therapy, dialectical behavior therapy, EMDR, and medication-assisted treatment — with holistic practices like mindfulness, yoga, and nutritional counseling.
We believe that sustainable recovery is built on understanding the underlying factors that drive substance use, developing healthy coping mechanisms, and rebuilding meaningful connections with family and community. Every treatment plan at our facility is tailored to the individual.
