Dr. Chynn, Has been an extremely caring physician in my experience. Only just recently, Dr. Chynn took the the time on a Sunday evening while dining with his family, to give both me and my brother who lives in another state input and help viz. my brother's situation. Dr. Chynn provided us with an excellent referral for a colleague of his in SFO whose highly regarded. The several office visits that I've had in the past - Dr. Chynn has been most attentive, and clearly is highly qualified experience and knowledgeable. Exceptionally so. The office can be lively, however that in no way reflects on the excellence of the medical services provided.
