William Pitt Sotheby’s International Realty has announced its expansion with a new office in Niantic at 24 Pennsylvania Ave.

The new office joins the firm’s Old Lyme brokerage to become its second New London County location.

“We are excited to grow our presence in this highly sought-after market region by establishing a key office location in one of New London County’s premier destinations,” said Paul Breunich, the company’s president and chief executive, in a release.

Managing the new office will be Heather Gagnon, who also serves as the manager for the company’s Old Lyme brokerage. Gagnon was recently named William Pitt Sotheby’s International Realty’s Manager of the Year, chosen for the honor from among 17 managers company-wide.

In 2020, Gagnon significantly increased the Old Lyme office’s production levels, attracting some of the region’s highest producing agents by dollar volume, according to the release.

The new Niantic office will start with 21 sales associates including top producers Stacey Wyeth, Deb Fountain, Leslie Timmons, Beth Brucker, Maris LeBlanc, Dave Thomas, Patty Heenan and Bonnie Nault.

A grand opening celebration is planned June 23 at the new location.
