IRC is excellent, and located around the Bay Area (there are usually at least a few people carpooling down from Oakland) - https://www.insightretreatcenter.org
It's the retreat side of IMC (https://www.insightmeditationcenter.org). You might listen to some of their talks or read some of Gil's writing[1] to see if it's what you are looking for. It's in the Vipassana tradition, though a number of the teachers had affiliation with the SF Zen Center.
