Biohazard and Crime Scene Remediation in Monsey, NY

Monsey is a hamlet and census-designated place (CDP) in the town of Ramapo, Rockland County, New York, about 30 miles northwest of New York City.

Monsey takes its name from the Munsee band of the Lenape people, and its railroad station was built in 1841 when the New York and Erie Railroad came through Monsey Glen, a former Native American encampment where artifacts and rock shelters have been found.

Monsey is the largest center of Hasidic Judaism in the United States outside New York City, home to roughly 5,400 Hasidic households — about 4.2% of the world's Hasidic population.

The 2020 census counted 26,954 residents in Monsey, a jump of 46.4% from 18,412 in 2010, making it one of the fastest-growing communities in New York.

Monsey is remarkably young: the median age at the 2020 census was just 15.7 years, and 55% of residents were under 18, reflecting the community's large families.

Despite its density — nearly 11,800 people per square mile packed into about 2.3 square miles — Monsey had only 5,002 households in 2020, because its average household is so large.

The hamlet's transformation began in 1944 when Rabbi Shraga Feivel Mendlowitz founded Beth Medrash Elyon, a yeshiva for Torah teachers; by 1997 Monsey had 112 synagogues and 45 yeshivas.

In 1979 Monsey became the American campus of Jerusalem's Ohr Somayach yeshiva, one of several major Torah institutions headquartered in the hamlet.

Yiddish is a living language in Monsey — about 41% of residents speak Yiddish at home and roughly 7% speak Hebrew.

The all-Hasidic village of Kaser lies entirely within Monsey's borders, surrounded by the hamlet on all sides.
