About Us

Our Company Background

Founded in 1936, Nassau Financial Federal Credit Union has over 80 years of service to the Nassau County community.
Originally chartered to serve employees of the Nassau County Courthouse, over the years our charter has expanded to include everyone who lives, works, worships, goes to school or volunteers in Nassau County. Today, we have over $400 Million in Assets and serve over 23,000 members.
As a financial cooperative, Nassau Financial serves its members with higher rates on savings and lower rates on loans. Because membership lasts a lifetime, people can remain a member even if they move, change jobs or retire out of state, simply by maintaining a $5 minimum balance in their Primary Savings account. Once you are a member of Nassau Financial, your immediate family members can join too.
We offer a full suite of retail banking products, services and financial solutions for consumers and small businesses. On a monthly basis, our members rate us with high marks for the service we provide to them in meeting their banking needs.

About our Service Mission

The Credit Union philosophy of "People helping people" aligns with Nassau Financial's Service Mission, which is: "Improving the financial well-being of each member and the communities we serve." We firmly believe that corporate volunteerism and philanthropy is not done simply to build our brand, but to create positive ripples in the community by helping people in need, raising awareness about specific problems or issues, and making our neighborhoods a better place.
While we are a financial institution, we believe we have a responsibility to the communities we serve to make a difference in the lives of the people on Long Island. We achieve this by also implementing our Corporate Philosophy of "Building valued relationships by delivering financial solutions."
We encourage you to visit us often, online at and in person at our branches to learn more about our financial offerings as well as our activities in the community.
