A New Beginning and Fresh Start
At Fresh Start of California, we envision lasting freedom from addiction and long-term recovery for every individual who seeks our care. To reduce the risk of relapse, we incorporate the latest advancements in addiction and behavioral sciences, along with evidence-based treatment methodologies, into every aspect of our program.
We are among a select group of addiction treatment centers nationwide that utilize the proven science of Medication-Assisted Treatment (MAT) to effectively address opioid, substance, and alcohol use disorders.
We recognize that each person seeking treatment is a unique individual, shaped by a combination of genetics, heredity, environment, and life experiences. Rather than relying on generic or standardized approaches, our clinicians develop personalized treatment plans tailored to each patient’s specific needs, grounded in best practices and clinical expertise.
Our mission is to help every patient confront and overcome addiction, reclaim their sobriety, thrive in recovery, and build a fulfilling future.
