Day One is most known for our residential substance use disorder treatment program for youth, the only one in Maine for teens 13 to 18. We also provide a full continuum of substance use and mental health services designed to reconnect individuals, youth and families to paths of healing and recovery.
We have grown from a single small treatment facility in South Portland to an agency that has been providing substance use and mental health treatment services to youth and families for over 50 years.
