Our History of becoming the largest Credit Union of the Northeast begins in 2003 with a unanimously approved community charte ... r application to serve all Long Islanders. With branches across Long Island, we serve individuals, small businesses, and large organizations alike with the same passionate commitment towards fulfilling our vision of enriching lives. In 2016, our charter was amended to open up membership beyond the borders of Long Island to anyone, anywhere. Now that we are able to share our Vision & Mission with everyone, one can become a member-owner of Bethpage by opening a $5 share account. Just like when we first opened our doors for Grumman employees in 1941, we’re still keeping to our promise to always meet your changing needs with extraordinary service and value. read more
