A Message from the Supervisor

“Welcome to Islip, the 3rd largest town in New York State, but with an endearing small town feel. We are so proud of our town…our beaches, golf courses, marinas, parks, housing opportunities for all, businesses, industrial parks, healthcare and educational institutions including our own Islip MacArthur Airport that provides many job opportunities. I sincerely hope you find this website helpful.” — Angie
