NEW MILFORD — Mayor Pete Bass this week apologized on behalf of former Mayor David Gronbach in a news release and letters to town families. Bass, in the release, said Gronbach disclosed residents’ personal information when he criticized a local nonprofit last summer. Bass said an apology was needed.

Gronbach, in August, wrote an open letter questioning why the Children’s Center, a nonprofit in town, provides state-subsidized day care to some families earning more than $100,000 a year. The information Gronbach posted, which did not identify families by name, was also shared under a public records request with Hearst Connecticut Media. Days later, the state Office of Early Childhood wrote that his post constituted “breach of contract” with the state by disclosing “family-level personal information that is considered confidential.”

The state “was very clear prior to my taking office that a letter of apology was required from the town,” Bass said in the release.
