I have lived in San Ramon for about 25 years. It is a small area with a number of large adminstrative offices for Chevron, Toyota, SBC, and some various smaller companies. Depends alot on what type of work she is looking for. Many small company operations as well. Best thing for her to do is come and stay a few days (various nice hotels) and do some job hunting.
Cheers!
she already has the job, she will be going to work for Chevron. If you live that way, what are the differences in these 3 cities? She has been raised in Houston, Texas.
