St. Joseph Elementary School is a small Catholic school located in the heart of historic Mendham Borough in Morris County, New Jersey.
The education mission of St. Joseph School encompasses four dimensions: message, community, worship, and service.

Hi there, our daughter graduated from St. Joseph's 1993, we felt the best education for her, it was the stepping stone for years to come. My question is, has the school reopened? We were very sad when we read it had closed several years ago, thank you. It will always hold a special spot in our hearts.

We 100% recommend St. Joseph School! We moved our children from the public school to St. Joe's several years ago and have been so impressed with the quality of education they have received. My son graduated last year and now attends Delbarton. I do not believe he would have had the same drive and quest for excellence had he not been a student at St. Joe's.
