*Note regarding the difference between open and closed meeting...

Closed to public - These meetings are for addicts/alcoholics only. To attend a closed meeting just show up if you have a substance abuse problem. No invitation is needed. If this is your first meeting, we recommend arriving a few minutes early. Closed meetings are closed to those who are not addicts/alcoholics.

Open to public - These meetings are open to anyone - addicts/alcoholics, their loved ones, anyone in the community, etc. Just like closed meetings, open meetings do not require an invitation to join.
