NBT Bank to Open New Branch in Portland

PORTLAND, ME (October 29, 2025) – NBT Bank has announced plans to open a new branch in Portland at 191 Marginal Way.

“We’ve seen tremendous growth in our customer base and team members in recent years,” said NBT’s Maine Regional President Michael O’Reilly. “We are excited to expand our presence in the community with our new Bayside branch, which will complement the services provided by the team based at our regional headquarters at 5 Widgery Wharf in Portland.”

Construction is underway on the 1,700 square-foot banking location, which will include a walk-up ATM and night drop services. The branch is anticipated to open later this year or in early 2026.

Since NBT Bank first established a presence in Maine in 2014, the bank has steadily grown its customer base and locally based team. NBT will continue to offer banking services from its Maine regional headquarters on Portland’s waterfront with the Bayside location becoming the bank’s first walk-up retail banking location in the state.
