When I lived in Pasadena, CA, I attended a wonderful DBSA chapter with substantial meetings at a hospital.
Here in Phoenix, NAMI and DBSA have minimal services. There are a few locally run support groups. Maricopa County has a list of support groups for all subjects that may have been updated for covid. Each group has its quirks. The bipolar group on W Thunderbird (very large at one time)did not have a contact list. I should check on their status. The founder of the downtown bipolar group was retiring to another area last I heard. They posted an agenda in advance.
