Get to know the NECEC staff.

Joe Curtatone, President

Before stepping into the role of NECEC President, Joseph A. Curtatone forged a reputation for being one of the most innovative mayors in the United States as the nine-term Mayor of Somerville, MA. That includes Somerville being named one of only 95 cities in the world to make the CDP Cities A-List for climate planning and action. He also spearheaded a comprehensive net-zero action plan for his city with a strong focus on equity.  During his tenure, Curtatone embraced data-driven decision making, employed systems-based solutions to community issues and was an innovator in healthy city initiatives. He has forged regional coalitions to tackle issues around transportation, housing and COVID-19 pandemic response. He also worked to establish Somerville as a leader in climate technology, recruiting Greentown Labs to the city, where it has been steadily growing since 2013. Thanks to his pursuit of cutting edge industries, Somerville saw its workforce increase by more than 40% during his tenure as the city became the home to billions of dollars of new economic activity. Curtatone also did significant work to reshape the city. In 2014, Somerville opened the first new station in Greater Boston's core light rail transit system in 27 years, and soon it will open six more new stations as part of the first major expansion of that system since the 1980s. In addition, during his time in office Somerville built a network of more than 40 miles of bicycle lanes inside a city of just 4.1 square miles. He is a graduate of the Harvard Kennedy School, the New England School of Law and Boston College. A father of four, Curtatone also has been a longtime high school and youth sports coach.
