Which major hedge funds and I-banks have offices in northern
California? (Don't count sales offices. I'm trying to find out places
where an analyst could work.)

Got it - I understand what types of offices you're looking for. But
analysts with your qualifications often work at more than I-banks and
hedge funds.

Will you consider: 
* Trusts, Except Educational, Religious, and Charitable (personal
trusts, estates, and agency accounts)
*  Real Estate Investment Trusts  
* Unit Investment Trusts, Face-Amount Certificate Offices, and
Closed-End Management Investment Offices
* Commodity Contracts Brokers and Dealers 
* Pension, Health, and Welfare Funds 
* Accident and Health Insurance (self insurers) 
* Hospital and Medical Service Plans (self insurers) 
*   Fire, Marine, and Casualty Insurance (self insurers 
* Trusts, Except Educational, Religious, and Charitable (vacation
funds for employees)
* Short-Term Business Credit Institutions (e.g. Visa)
* Oil Royalty Traders 
* Investors, NEC (commodity contract pool operators)

Write back here; I'll compile your answer. - Mary

Hedge funds and I-banks are my number one priority.

If you care to include some of the major northern California employers
in these other areas, that might also be useful, but there's no need
to put together an exhaustive list for them at this point.
