George Twigg, the state director for U.S. Rep. Peter Welch (D-Vt.), is leaving his post later this month.

Twigg, who replaced Tricia Coates in March 2015, said he's moving with his wife to Boulder, Colo., where he’ll work as a policy analyst for the Boulder Board of County Commissioners. “Unlike Vermont, Colorado has a pretty robust county government system,” he said.

As Welch's top Vermont staffer, Twigg oversees the congressman's outreach and constituent service operations, coordinates his in-state schedule and serves as Welch's eyes and ears in the district.

Of his time in Welch's office, Twigg said, “It’s been an especially interesting time to be in national politics, with the 2016 elections." It required, he continued, “trying to not just respond to the tweet of the day but think about long-term solutions to real challenges and issues that Vermonters have.”

Before he went to work for Welch, Twigg was public affairs director for the Vermont Energy Investment Corporation.

Welch’s office has yet to hire a replacement, according to Twigg.
