Marshall honed his marketing expertise in the financial sector, launching his career at CitiBank and continuing at leading regional banking institutions such as Crocker Bank and Security Pacific Bank, where he introduced highly successful new products in the retail banking and trade finance areas.

Since founding Martin & Stowe in 1991, Marshall has worked with clients across a broad range of categories. He brings, naturally enough, an expertise to clients in the financial sector and has a specialized understanding of technology products. Regardless of the product or category, Marshall combines in all his work an intuitive grasp of issues with an ability to cut to the core of what motivates the consumer. It is this mix of talents that allows Marshall to work very effectively with clients to deliver products, marketing and advertising programs that respond to real consumer or business needs.

Marshall earned his MA and BA in Political Science from San Francisco State University.
