David Gronbach, a former New Milford mayor, is running for the state’s 30th Senate District as the Democratic candidate.

The seat, which represents 14 towns from Brookfield to Massachusetts, is currently held by Republican Craig Miner.

Gronbach, 44, of New Milford, was mayor from 2015 to 2017. He unseated Pat Murphy, a five-term incumbent, before losing to Pete Bass, New Milford’s current mayor.

As mayor, he oversaw the construction of the first part of a greenway along the Housatonic River and turned the former John Pettibone School into a community center. He faced criticism for how he handled the Pettibone project though.

He’s campaigning on a platform of holding the line for middle class and lower income families, relieving the financial burdens placed on residents and getting Western Connecticut a seat at the table to demand more resources for economic development, conservation, tax relief and education.

Gronbach is a lawyer and Medinstill’s director of business development. He also offers government consulting services, as well as pro bono work for individuals and families seeking asylum in the United States.

He is married with three children.
