What Our Members Are Saying About Sayville:

Daniel D.

Sayville, NY

“The staff at Island Federal Credit Union are amazing!!! They are so friendly and willing to help no matter what I ask of them! I was thinking of switching banks at one point to one that was closer to my home but it’s the kind people at Island that made me continue doing business here and taking that extra 20 minutes to get business done! That’s how incredible the team is here! :)”

“I have had nothing but wonderful experiences at our Sayville/ Bohemia location. The staff is incredibly kind and patient. I’m actually going to close my other bank account and solely use Island Federal. I would be extremely proud and grateful if the staff at this location worked for me.”

Their knowledge of the credit unions products and services and professionalism are unlike anything I have ever experienced at other financial institutions. The teamwork they display is rare and admirable in todays world where most people are only interested in their own tasks.
