Under his leadership, 7 NYC Business Solutions Centers were established that secured more than $200 million for small businesses, and 17 workforce centers were refocused to place 200,000 people in jobs. He also forged new partnerships with groups including the Initiative for a Competitive Inner City, Goldman Sachs 10,000 Small Business Program, Interise, and the Kauffman Foundation.

Prior to his service with the City, Walsh served as President of Charlotte Center City Partners in North Carolina, an organization dedicated to improving and growing Charlotte's central business district. He led the Center City 2010 Master Plan that laid the groundwork for significant private and public investments in the core of the city including more housing, retail development, an NBA basketball arena, a minor league baseball stadium, cultural facilities, a light rail line, and parks. He also initiated the recruitment efforts that attracted Johnson & Wales University to the Center City.

Walsh holds a Bachelors in Political Science and Masters in Public Affairs from Fordham University. He also participated in the Senior Executive Program in State and Local Government at the Harvard Kennedy School.
