By the time next week rolls around Investors Bank will have doubled the size of its branch network in New York’s Nassau and Suffolk counties with the closing of an acquisition first announced July 2019.

On Thursday, Short Hills-based Investors Bank said it will complete its move to acquire Gold Coast Bank on April 6, with six former branches on Long Island and Brooklyn set to transition to Investors Bank locations on April 4 and April 5.

The $63.6 million-valued deal was approved by the FDIC earlier this month.

In a statement, Investors Chief Executive Officer Kevin Cummings said the community bank aimed to create a seamless transition for its new customers changing over from Gold Coast, and that it contributed significant resources toward those efforts.

In conjunction with COVID-19 best practices and safety and health care guidelines the former Gold Coast branches will open to provide appointment-only, in-branch service from 9:00 a.m. to 4:00 p.m. on weekdays and from 9:00 a.m. to 1:00 p.m. on Saturdays. Drive-thru banking will also be open during those same service hours.

Investors Bank said it also offers drive-up banking at its Commack, East Northport, Franklin Square, Merrick and Mineola locations.

“We are open for business and committed to providing you, our newest clients on Long Island and in Brooklyn, the most complete suite of banking products and services,” Investors New York Market Executive Ana Oliveira said in a prepared statement. “Our mission is to deliver an incredible level of service when you visit your branch, contact our NICE team, or use our robust online and mobile banking services.”

The NICE Team in its Client Care Center is available from 8:00 a.m. to 7:00 p.m. on weekdays and 8:00 a.m. to 6:00 p.m. on weekends at (855) 422-6548.

As of Dec. 31, 2019, the most recent information available, Investors Bank had total assets of $26.7 billion; Gold Coast had $559.8 million.
