Emergency Crime Scene and Biohazard Cleanup in Selden, NY

Selden is a hamlet and census-designated place in the Town of Brookhaven in Suffolk County, New York.

The farmers who settled the area in the mid-18th century called it Westfield, and one of its best-known early residents was Captain Daniel Roe, a veteran of the French and Indian War and the Revolutionary War for whom Captain Daniel Roe Highway is named.

When a post office opened in 1852, the name Westfield was already taken upstate, so the community renamed itself for Judge Henry Selden, who had promised to do "something handsome" for the honor.

As of 1885, Selden had only 88 residents and a Presbyterian church built in 1857, and its farms were known for melons and early garden vegetables.

Around 1897 the popular cross-island Bicycle Path was completed and ran through Selden.

The Suffolk County Tuberculosis Sanatorium opened in Selden in 1916, and in 1961 its grounds became the main Ammerman Campus of Suffolk County Community College, which enrolls more than 11,000 students.

Selden had 21,262 residents at the 2020 census, and at the 2000 census it had 21,861 people in 6,809 households.

Selden's main commercial thoroughfare is Middle Country Road, New York State Route 25, which runs the length of the hamlet.

A fire lookout tower stood on Selden's Telescope Hill from 1919 to 1959.

Serious suburban development did not reach Selden until the early 1950s, when a place that had held about 131 residents in 1931 began its transformation into a suburb of more than 20,000 people.
