Massachusetts CIO John Letchford will leave his post effective Dec. 16 for a position as a senior IT strategist at Tufts University. A former Procter and Gamble executive, Letchford has served in various technology roles for Massachusetts over the past several years, and has been state CIO since 2011.

A 2013 Government Technology Top 25 honoree, Letchford is known for his collaborative style, forging new partnerships with officials at other levels of government, and leading state initiatives, including an infrastructure consolidation project.

The top tech spot in the state will go to a familiar face -- Boston CIO Bill Oates (at left), who will assume the position in January. Also a past Top 25 award-winner, Oates has led the city's technology efforts since 2006, overseeing significant open data efforts, and the creation of citizen-focused apps to drive civic improvements.
