Islip Town Attorney Mea Knapp is resigning from the position to take on a part-time role in Supervisor Angie Carpenter’s office.

At Tuesday’s board meeting, Carpenter nominated Deputy Town Attorney John DiCioccio to replace Knapp in the $120,000-a-year job.

“We can’t thank you enough for your service to take us through this initial period in 2016,” Carpenter told Knapp at the meeting.

Knapp’s last day is Monday.

DiCioccio, 32, of Bay Shore, first joined the Islip Town attorney’s office in 2010 as assistant town attorney and oversaw the town’s Division of Code Enforcement and served as counsel to the Industrial Development Agency.

He graduated from the College of the Holy Cross with a bachelor’s degree in economics and earned his law degree from St. John’s University in 2009, according to his resume.

In addition to Carpenter, council members Steve Flotteron and John Cochrane Jr. voted to approve DiCioccio’s appointment. Council members Trish Bergin Weichbrodt and Mary Kate Mullen abstained from the vote.

In a phone interview after the vote, Bergin Weichbrodt said the town should have done a wider search for Knapp’s replacement.

“I think that an open vetting process should have taken place and it didn’t. This is an extremely important job,” Bergin Weichbrodt said. “I think with the responsibilities that go with this particular job, a serious search should have taken place.”

Mullen did not respond to a call for comment.

Knapp said she would stay on in Carpenter’s administration in a yet-to-be-determined part-time role.

“I’m willing to serve in whatever capacity, but this works better for me,” she said after the meeting.

Knapp has previously served as president and chief executive of the Suffolk Regional Off-Track Betting Corp. and formerly was an assistant Islip Town attorney before leaving for a private firm. She was hired last year by Carpenter as her town chief of staff and then appointed town attorney in January.
