What to Expect During Rehab Serving Placentia, CA

Personalized Addiction Treatment in Placentia
No two addiction stories are alike. That’s why our team performs a thorough assessment of each client’s medical history, substance use, mental‑health conditions and personal goals before recommending a course of treatment. By tailoring therapy, medication and lifestyle interventions to the individual, we ensure that each client receives the right combination of services at the right time.

Inpatient Rehab Placentia
Cornerstone’s inpatient program takes place at our Orange County campus, but it serves many Placentia residents. Clients live on site for about four weeks, immersing themselves in therapy, group work and wellness activities without the distractions of everyday life. This secure environment allows individuals to focus on healing and build a foundation for lasting sobriety.

Intensive Outpatient Program (IOP)
Our IOP helps clients transition from residential treatment or enter care while maintaining work or school commitments. Sessions include individual counseling, group therapy, educational workshops and relapse‑prevention planning. IOP can be a critical support for Placentia residents who want intensive services without a residential stay.

Partial Hospitalization Program (PHP)
For individuals who are dealing with substance use, mental health, or behavioral issues and need an in-depth level of care without the full hospitalization requirement, a Partial Hospitalization Program (PHP) may be just what they require for their recovery journey. PHP's provide clients a crucial step towards achieving healthy lifestyles free from drugs and alcohol addiction along with restoring happiness to their lives.

Extended Care Programs
Cornerstone's Extended Care Program (ECP) is here to help bridge the gap between drug and alcohol treatment and leading a successful life in sobriety. Even with renewed hope from completing initial rehabilitation, relapse can still be an issue for many individuals. To mitigate this risk of relapse occurring, ECP provides additional support throughout one’s recovery journey beyond their existing treatments - giving greater assurance on sustaining long-term addiction freedom.

Sober Living in Placentia
At Cornerstone Sober Living, we strive to provide adults aged 18 and over with a secure and supportive environment conducive to their continued recovery. Our licensed recovery homes feature six residents per house, each managed by a live-in manager available 24/7 in case of any housing issues. Clients are given the freedom they need while being strongly encouraged towards independence - making it an ideal setting for those enrolled in our Extended Care Program, Day Treatment (PHP), or Intensive Outpatient Treatment program!
