Founded in 1889 as a Mission Church of the Episcopal Diocese of Newark our church is proud of its history of serving God and the greater Pascack Valley community. The first service was held by Reverend Thomas Stevens on January 29th, 1890 in the home of Mr. A.J. Fincke, located on the southeast corner of Patterson and Park Streets.  Subsequently services were held in the room over the existing Erie Lackawanna railroad station in the borough until the first church was erected on Park Street. Services were held there until March 1894 when the mission moved to its present location at the corner of Hillsdale Avenue and Trinity Place. Holy Trinity transitioned from mission status to a full parish in May 1945. In 1965 the old church was razed and the present church was completed and dedicated in 1966.

In the years since then a number of renovations have been made to accommodate the needs of the parish.

Over the years, Holy Trinity has gone through many renovations to make it the remarkable place it is today, including the construction of a new church office in June of 1978, a new chapel in January 1980, and office relocation and remodeling of our kitchen in 2002.
