I don't agree with previous reviewers. I did several major jobs in her office (root canal, 4-unit brigde) and all ended up with success. I also won't say that office is expensive, rather average. Their customer service is OK too. I'd rate it B+.
I'm quite picky and have attended several dentists in SF Bay area, but ended up going to Dr Zhalkovsky office. Reasons - I can always discuss my treatment and understand my options with this doctor. No pain and no problems with past treatments.
