Loudoun Serenity House's mission is to provide high quality affordable recovery residential services, peer-based mentoring, education and advocacy to enhance the lives of people seeking recovery from substance use disorder. They welcome both men and women (18+ years old) from any geographic location with at least 30 days sobriety. Stays can range from one (1) to eighteen (18) months. Loudoun Serenity Houses are close to public transportation and within walking or biking distance to grocery and retail shops. The women's house can accommodate up to eight (8) women and the men's house can accommodate up to six (6) men. Residents must have completed a treatment program or are currently enrolled in a program with a primary diagnosis of Substance Use Disorder. The optimal length of stay for a resident is 12 months although some may stay shorter or longer. Residents will work and pay rent while establishing a recovery program in the Loudoun County self-help community.
