ISO social groups and organizations

Hi Neighbors. Kind of a different request. I moved into the city last year from Suburbia. I am looking for some groups and Community organizations to join for social reasons. I am certain there are many in the city. I just don't know how to find them. I have tried Meetup which has been somewhat helpful. Many of these actually occur in Suburbia however. My interests tend to be spirituality, Arts, cultural, writing, yoga, health, painting, photography. I'm not much into organized religion so formal churches typically don't work for me. I'd appreciate any suggestions at all based on the information I have given. Thank you very much. And happy holidays! Diane
