I am seeking a space to host a family constellation on the evening of June 15th, and possibly future such events as well. We'd need room for a circle of 20-30 people with a nice space in the center of the circle to do the work -- 20x25 or something in that range is probably ideal.

A nice mediation or movement space would be wonderful, so long as there are no big mirrors; even a large office or living room can work well.

I know there are probably many places out there that would suit this purpose -- I just don't know where they might be!
Location-wise, Sebastopol, Cotati, Rohnert Park or Santa Rosa all would be great...

Thanks very much.
