They’re the founding forces behind the Insight Meditation Society in MA, which although isn’t the West Coast, is perhaps the most influential force in popular Buddhism in the West.
Kornfield also set up Spirit Rock Meditation Centre in California though, which gets tens of thousands of visitors a year.
Having dived really quite far into Buddhism over the past five years, I’ve found their flavour of Insight Meditation (as per the New Burmese Method based on Mahasi Sayadaw’s teachings) absolutely life changing.
A great read, thank you for sharing.
If anybody is interested in reading further - Goldstein’s podcasts, Mahasi Sayadaw’s writing, Kornfield’s introductory texts and ANYTHING by Bhikku Bodhi are a phenomenal place to start.
