The Yarmouth Chamber of Commerce announced that Mary Sundeen will serve as its next executive director. The business organization has not had full-time leadership for several years.
“I absolutely love an opportunity to work with the community and to strengthen an organization,” said Sundeen.
Sundeen has led several nonprofit and for-profit organizations, including Midcoast Humane. Her volunteer experience includes 20 years of service in the United States Coast Guard Auxiliary and as a board member for the KISMET Foundation, a Yarmouth-based arts organization.
“Mary’s track record of strategic expertise, and guiding organizations through growth and change is exactly what our organization needs to thrive,” Yarmouth Chamber of Commerce board President Marshall Wallach said in a release.
Sundeen said as executive director, strengthening businesses in the community is her first priority. She also wants to bring new businesses to Yarmouth. To do so, Sundeen said she is excited to further mesh the efforts of the Yarmouth Chamber of Commerce and the town’s economic development department.
“I think that that will benefit the business community and the citizens of Yarmouth,” she said.
The Yarmouth Chamber of Commerce also announced Adrienne Nardi as its event director for this year’s Yarmouth Clam Festival. Nardi served as the chamber’s executive director from 2016 to 2022 and is familiar with the importance of the Yarmouth Clam Festival to the community, she said. Nardi also owns her own event consulting business.

“Adrienne’s passion for the Clam Festival is palpable, and we are just incredibly grateful to her for coming back and doing this,” said Sundeen.
The Yarmouth Clam Festival, taking place July 17-19 this year, draws over 100,000 visitors annually. Nardi emphasized how the festival heavily relies on Yarmouth volunteers and in turn supports many nonprofits in the town such as youth sports teams.
“It’s a unique thing of such a massive event, to creating such a small town atmosphere,” said Nardi.
