Prior to founding Keswick Consulting, Matt worked for three Massachusetts governors, where he held several high-ranking personnel and policy positions. As deputy chief secretary, he was responsible for overseeing more than 2,500 political appointments to several hundred boards and commissions, including many regulatory authorities. As a result, Matt forged many strong business and political relationships that endure to this day.

In his capacity as assistant chief of staff, Matt was designated as a key administration liaison to the federal government, which included oversight of the Commonwealth's Office of Federal Relations in Washington, D.C.; he also served as designee to the National Governors Association and the New England Governors Conference/Eastern Canadian Premiers.

In addition to representing clients at all levels of government, Matt is strategically aligned with CanAm Strategies, a Boston and Montreal-based government relations and business development firm. Matt works in partnership with CanAm to further develop business and political relationships between entities in the United States and Canada.

Since departing state service, Matt has been active on dozens of political and philanthropic campaigns; his fundraising prowess has translated into millions of dollars raised for the various finance committees on which he has served.

Matt is a member of the Board of Trustees at Cardinal Spellman High School and the Board of Diesel Direct, as well as a past member of the Board of Trustees at Bridgewater State University and the Board of Directors of the Massachusetts Educational Financing Authority.
