About our office and staying over in Petaluma for those from out of town: 

The Metta Center’s office is located in the heart of Petaluma, California. It is wheelchair accessible from the side of the building by the parking lot. Street parking has a two hour limit in front of and around the Metta Center’s offices, and unfortunately, folks will get ticketed if they ignore the signs and/or forget to set a timer. We are not having guests visit at this time due to the pandemic.

Unfortunately, we do not have a residential center, so if you plan to stay overnight or desire to stay for an extended period, you will need to find/research your own accommodation in the area and be able to manage your own transportation. Buses run from SF and Santa Rosa Airports to Petaluma and there is a SMART Train from Santa Rosa and San Rafael. The office is a very short distance (for walking or wheeling) from these stations. Please direct your questions to info [at] mettacenter [dot] org. If you would like to gift us with a residential center and/or would like to offer your space as a location for Metta guests to stay when they come to town, please don’t hesitate to contact us!

’63 Boycott Screening

On October 22, 1963, more than 250,000 students boycotted the Chicago Public Schools to protest racial segregation. Many marched through the city calling for the resignation of School Superintendent Benjamin Willis, who placed trailers, dubbed ‘Willis Wagons,’ on playgrounds and parking lots of overcrowded black schools rather than let them enroll in nearby white schools. Blending unseen 16mm footage of the march shot by Kartemquin founder Gordon Quinn with the participants’ reflections today, ’63 Boycott connects the… read more

The benefits of the hope tank are many, including but not limited to: getting to practice listening… read more
