Watertown has had a challenging year. Yet, working together, we’ve made a lot of progress in building a stronger Watertown. I’m John Gannon, and I’ve had the honor of serving as one of your four at-large Town Councilors; that means I serve each and every Watertown resident. I grew up here and graduated from Watertown High School, and I chose to stay here for its community strengths, just like most residents who chose to come here. I went to Brown University, then Suffolk University Law School, and began a successful career as a local government attorney. For the past 25 years, I’ve been working as a municipal attorney for more than 100 Massachusetts communities, tackling issues that Watertown is now facing. More than anything I’ve achieved, I’m a proud dad of Will, 18.


Watertown is on the Move!

We’re building new schools; strengthening our Town Charter to provide more openness and resident engagement; preparing for new leadership to replace our retiring Town Manager; fighting for climate readiness, affordable housing, more parks and open spaces, neighborhood-friendly development and a welcoming community for all. I’m proud of what we’ve accomplished during my last two years as your Town Councilor At-Large, but we can’t stop now! I would be honored to have one of your four votes for Town Councilor At-Large, so that I can work with you to continue our progress! Thank you.
