Diane Giese, Head Librarian, has an English degree from Mount Holyoke College and much experience as a non-profit administrator and former restaurateur.  A transplant to the Midcoast, she is still struck by the beauty and people of Thomaston, and lives in town with her rescue dogs in view of the St George River.

Melissa Harjula came to Thomaston Public Library first as a volunteer.  During the summer of 2015 she was a key leader for our “40 Days of Summer” program and is often helping our patrons at the circulation desk.  A native of Cushing, Missy, now living in Thomaston, loves her many animals.



Blake Donaldson has been with the library since 1998.  While he has expertise in nearly every operation of TPL, his current specialty is being the Catalog Development guru. Made in Maine and educated at University of Maine at Orono with a major in history, Blake lives in Thomaston with his lovely wife Alethé.



Caroline Ward-Nesbit is a native of Maine and comes to the library with a degree in Chemistry as well as a decade of customer service experience, and a love of all things library related. She enjoys camping and hiking with her husband John and has been learning to sew.


Toby Mergendahl has been part of the 40 Days of Summer staff since 2016, and join the regular library staff in 2018 while he takes a gap year prior to starting college.
