The Sippican Historical Society is mulling a change in operations following the sudden, and seemingly inexplicable, resignations of several board of director members and the executive director last month.

Former Sippican Historical Society President Sally Conkright, Executive Director Kimberly Teves, two board members and the vice president stepped down on Aug. 21.

“Over the years, these individuals have served in various capacities on a team that has skillfully led the organization, bringing energy, expertise and a shared dedication to preserving and celebrating the rich history of our wonderful town,” Conkright wrote in a letter sent to society members.

When asked what prompted the departure of so many members, Conkright said she couldn’t speak on behalf of others.

However, Conkright cited an increased focus on her career as a consultant as her reason for leaving. That work will require her to spend more time in New York City.

“I am confident that the remaining SHS officers and Board Members will work to ensure stability and continuity throughout the organization, while moving forward with creativity and vision,” Conkright wrote.

In the wake of the resignations, a new president of the board of directors has been elected and another member is expected to join the board on Sept. 24.

Historical Society Treasurer Judy Rosbe said Frank McNamee is the new president. Having founded the Marion Antique Shop in 1974, McNamee is well-known in the area for his interest in local history and antique acumen.

David Pierce, a Tabor Academy teacher who also serves on a handful of town committees, is the new vice president.

But it appears that the historical society will move forward without an executive director at the helm.

“We will be rethinking the position,” Rosbe said. “It might be some combination of a secretary and a bookkeeper.”

Teves was hired as executive director for the newly created position in October 2007.

Since then, she has developed many well received programs in the community, such as a lecture series where speakers connected to Marion touch on everything from local history to international politics.

Until November, Rosbe will volunteer so the historical society remains open the same amount of hours it would under an executive director.

After that, board members may consider new hours.

Sippican Week calls seeking comment from Teves and other board members regarding the resignations were not returned.
