  • Probation approved treatment program

    Cornerstone of Southern California offers a probation approved treatment program in Orange County for alcohol rehab or drug dependency specifically designed for people with legal problems as a result of their chemical dependency, and who qualify as a minimum risk offender. If your interest in treatment is precipitated by any very recent, relatively recent, or even pending criminal charges, it is of the utmost importance (prior to even an arraignment hearing) to be proactive in entering the treatment setting and seeking professional assistance.
  • Cornerstone Family Program

    Cornerstone believes that chemical dependency is a disease that affects the entire family. If you have a family member or significant other in treatment, you are strongly encouraged to attend the Family Program. Statistics show that when the family is involved in the treatment process, the success rate for recovery is much higher.
