The head of one of the region’s 10 biggest banks, Cambridge Savings Bank, said he plans to retire after slightly over 10 years at the bank’s helm.

Wayne Patenaude announced his decision in an internal email. The Boston Business Journal first reported the story.

But his retirement date is still uncertain, as the bank has yet to line up a successor, a bank spokesperson said, and he’ll continue in his post until such a successor is named.

“Wayne F. Patenaude’s retirement marks the culmination of a remarkable 16-year journey with Cambridge Savings Bank, including over a decade spent as President and CEO. We are immensely grateful for Wayne’s exceptional leadership and unwavering dedication, which have been instrumental in our growth and community support efforts,” the bank said in a statement.

Patenaude “is committed to actively participating in the CEO selection process” and a “seamless transition” to his successor, the bank said.

Since joining Cambridge Savings Bank in January 2013, Patenaude helped grow the bank from $2.5 billion in assets to $6.7 billion as of June 30 of this year, according to FDIC statistics. During that time, the bank also launched its wildly successful digital bank, named Ivy Bank, which collected $530 million in deposits in just two years.
