Sarah Martin last year became president of New York-based Mitchell Martin Inc., responsible for strategic initiatives including all client and sales activities nationwide. She also sits on the board of the national trade association TechServe Alliance. The company last year acquired TwentyPine, an IT staffing firm specializing in the Salesforce ecosystem, as part of a strategy to penetrate high-growth niche markets and expand the scope of its consultant network. The firm also expanded its traditionally northeast geographic footprint. A panelist this year at the Tech Up For Women Conference in New York, Martin also advocates for women through the Impact100 collective grant-making organization.
