Cornerstone, located in the foothills of the Great Smoky Mountains of East Tennessee, provides a place where substance abuse and mental health issues can be addressed head on, so that healing may begin. Our programs are based on the Bio-Psycho-Social-Spiritual model of treatment and the 12 Step approach to recovery, and we pride ourselves on the individualized treatment plans we develop for each and every patient, the goals of which are to dispel the darkness of their disease and allow that individual to function as a responsible, productive member of society.
