Bay Area Diving Dogs does have people from the East Bay. I don't know of one that is specific to that zone, least never heard about any.
There is a great spot off of 880 near the Marina. Don't know how well your dog does recall or swims near people/boats, but there is docks down there that I have jumped Dega. Worth taking a trip there to see.
You should join BADD. We practice in Redwood City when our leader finds time to meet us! LOL. We all should meet more often, but well life is just not permitting that for many of us right now.
Hope that helps,
Gianna & Dega
