Needs a location
The Portland Sunday Assembly is a new congregation that is emerging, based on a movement that started in the U.K. (Britain) by comedians Sanderson Jones and Pippa Evans. Sanderson Jones is coming to the USA to see if there are cities that have interest in starting a local congregation, and he will be at this first event.
Their mission is to celebrate life, and encourage people to "live better, help often, and wonder more." They have no gods nor supernatural tenets, so they are also known as a "godless" congregation. However, they also don't denigrate religion, so believers of all stripes might also feel welcome.
If you are interested, RSVP at their event site (free) so they can gauge community interest:
