Need a primary doctor in Northern California who is familiar with patients who have had WLS

Good morning ladies.  I recently relocated from Florida.  I had RNY in 2003 and other than some low iron issues, have not had any other problems.  However, my physician in Florida was familiar with bariatric surgeon.  I am currently trying to find a primary physician in either the Northern California area (specifically the Oakland/East Bay area) who is familiar with WLS.  I'd appreciate any help you can give me.

Thanks ladies!!!
