St. Andrew's, or St. Athanasius as it was originally called, was established in 1844 as an Archdeaconry Mission.Without a church building during the 1800's, the Mission community had to avail themselves of various locations for worship services. These included private homes, the Grand Army rooms of the American Legion, S. Deyo & Son's Department Store, and under the Village Hall. The Village Hall became the Opera House, and more recently,a restaurant. 

Between 1906 and 1912, with the influx of Episcopal families of engineers working on the New York City Aqueduct, land was acquired and the present church structure was built on the corner of Main and Oakwood Terrace. The church's cornerstone was laid on November 30th 1909, and the name changed to St. 
Andrew's. 

The vicarage was built in the late 1920's, and in 1949 an addition was added to the church allowing space for a sacristy and a small chapel or office. 

Over these 150 years, there have been 22 Priests-in-Charge at St. Andrew's. The Rev'd Ralph F. Fogg, became Priest-in-Charge in 1986. He was assisted by Deacon Frances McGinnis until 2002.
