GUILDERLAND — Attorney Judith Kahn has served on the board of trustees of the Guilderland Public Library since 2012, when she was appointed to fill an open post. She then ran and was elected to the board for a five-year term in 2013.

Kahn resigned as of Sept. 29, when other opportunities arose that she wanted to pursue, said board President Bryan Best.

Kahn moved to Guilderland in 1988 and, in 2003, was a founding member of the Guilderland Library Foundation and served on its board. In 2013, there were three candidates running for two seats, and Kahn received the most votes, above second-place finisher David Bosworth, who was the long-time chairman of the Democratic Committee in Guilderland and who died earlier this year, and above Carroll Valachovic.

Best called Kahn “one of the best trustees i’ve ever worked with” and “phenomenal.” She is “super bright,” he said.

Two years ago, Kahn spearheaded the creation of the library’s long-range plan, “which was a big undertaking,” Best said. In addition, she helped the board in its fiduciary duties, setting up a special audit committee made up of volunteer certified public accountants and others with auditing experience to help the board gain more insights into its own yearly audits.

A search committee has already advertised for and interviewed candidates, Best said, adding that he hopes that the position will be filled as of the next board meeting on Nov. 16. Each of the 11 trustees on the full board serves on two or three committees, he said, and when the board is down one member, and then, for instance, another member goes on vacation, it can be hard for committees to get work done.

Kahn could not be reached for comment.
