The Support Group Project is an online directory of support groups for families struggling with a loved one’s addiction.  Approximately 2/3 of all families are impacted by addiction, yet too often, these families feel alone, isolated and stigmatized as they struggle with the effects of this devastating disease.  Help us connect them – help us create a community of support across the country.

Registering your group is free, easy and only requires minimal updating. Families deserve to find support in their local communities – you will be helping families in your community find that place of comfort they need during this difficult time. Learn more about the Support Group Project.
