The story

How Syosset came to be

From Wikipedia’s history of Syosset.

Read it all →

The location of what is now Syosset was originally inhabited by Matinecock Native Americans. In the 17th century, European colonists – primarily the Dutch and English – began to settle the area.

In 1962, Syosset Hospital – the hamlet's local hospital – was established. Located on Jericho Turnpike (NY 25), the hospital's opening provided the growing suburban community with improved, local medical care and facilities.
