1. Do I have to register? - No. Our groups anonymous and no membership or registration is required. Just show up to the group that fits your need. (example-If you are Family you would go to a family closed group or an open group, If you are a person with a mood disorder you would go to a peer support closed group or an open group.

2. How much does it cost & do you take insurance? - Our groups are free, we do accept donations.

3. Can I come with my husband or wife to the meeting? - Each of our meetings are exclusive and anonymous. If you are a family member, only family should attend the family support groups.
