MATTAPOISETT — Shannon Finning, a Mattapoisett School Committee and Joint School Committee member, tendered her resignation from both boards in a written statement read by Selectman Jordan Collyer during the Mattapoisett Select Board meeting on July 20.

In the letter, Finning cited issues with School Committee Chairman Jim Muse as the reason she was resigning from the board.

“I am unwilling to serve a body that continues to select a chair who has treated me, personally, with disrespect and, of more concern, has, in my opinion, demonstrated unwillingness to hear from all constituents and effectively engage and communicate with parents and families in particular,” she said in the letter.

Collyer said he regretted her departure.

“I obviously hate to see Mrs. Finning go, with the great amount of knowledge that she brought to the board — the school committee, I should say — and we truly appreciate all her efforts over the last few years in that role,” he said.

Finning was recently hired as vice president of student services at the Massachusetts Maritime Academy. In her new role, Finning will be responsible for the direction, leadership and management of the student services division, including the dean of students and commandant's office, athletics, health services and public safety.
