Nassau Financial FCU Plans Expansion in New York’s Long Island Market

The $342 million Nassau Financial Federal Credit Union in East Meadow, N.Y., said Tuesday it is planning to open a new branch in Suffolk County in 2025.

This expansion comes after receiving the NCUA’s approval for the Nassau County-based credit union to include portions of adjacent Suffolk County within its field of membership.

“This is a significant step forward for us. For years, we’ve heard from residents of Suffolk County who wanted to join our credit union but couldn’t due to our charter limitation,” Nassau Financial President/CEO John T. DeCelle said in a prepared statement. “Now, we’re able to say, ‘Welcome!’ Expanding into Suffolk County gives us the opportunity to provide the same exceptional service and financial benefits that our Nassau County members have enjoyed for decades. It’s not just about growing our membership — it’s about deepening our impact and helping even more Long Islanders achieve their financial goals.”

Suffolk County is home to approximately 1.5 million people and more than 490,000 households. Seventy percent of the population is white, 19% is Hispanic/Latino, nine percent is Black and four percent is Asian. The median household income is about $105,000.

Nassau Financial’s 68 employees run four branches in East Meadow, Garden City, Oceanside and Oyster Bay, serving more than 15,000 members.

DeCelle credited data and analytics CUSO CUCollaborate in Washington, D.C., with helping Nassau Financial secure the NCUA’s approval.

“CUCollaborate’s guidance through the application process was invaluable,” DeCelle noted. “They helped us craft a comprehensive and compelling case for expanding our membership into Suffolk County, which ultimately led to NCUA’s approval.”

Nassau Financial said it expects to open a new branch in Suffolk County during the fourth quarter of 2025.
