Our Founding

The formation of Main Street Research was inspired by our founders' deep commitment to helping individuals, families and foundations become financially secure for generations. These are the very same values that inspire our team today: Trust & Reliability. We serve clients near our offices in the San Francisco Bay Area and New York metropolitan area. In today's technology-driven world we serve clients across the country as well as internationally.

Meet The Team

Your financial success is important to each member of our team. The only compensation we receive is based on either the value of your assets or its performance — depending on which fee structure best suits you. Additionally, each member of our team shares in the firm’s equity or revenue. Therefore, your expectations for investment performance, risk management and a high level of service are directly tied to each team member’s goals. The result is a mutually beneficial relationship targeted at meeting and exceeding your expectations.
