Our mission is to prevent or minimize the effects of mental illness, mental retardation, and substance abuse, and to enhance the quality of life of Loudoun County residents affected by these conditions.

The Department of Mental Health/Mental Retardation/Substance Abuse Services (MH/MR/SAS) provides services to mentally disabled Loudoun County residents, including mental health/substance abuse outpatient, emergency services, mental retardation case management, job coaching, adult foster care and early intervention programs, residential services and outreach in all three disability areas.

The Loudoun County Community Services Board oversees MH/MR/SAS programs and services, sets departmental policy and procedures, and determines priorities as mandated by the state of Virginia.
