Collier High School is a private, nonsectarian high school located in the Wickatunk section of Marlboro Township, in Monmouth County, New Jersey, United States.

The house and property were given to the Sisters of the Good Shepherd with the express purpose to create a residential program for girls with problem situations.

The school was transferred to the sisters in 1927 by Sara Steward Collier-Van Allen.

In the agreement of property transfer, Mrs. Collier retained a suite in the house until her death in 1963 and kept close touch with the school and its needs.

[3] The first capital improvement to the property was the addition of Smith Hall, a girls' dormitory.
