Founder and director, Dan Teller, a pioneer in the Montessori community, had long envisioned a school that would offer an affordable Catholic education with a Montessori approach. In 1997, he initiated a series of community meetings to assess public interest in the formation of a Catholic Montessori school. These produced a groundswell of support.

Local parents and educators mobilized, and a core group formed a Board of Directors. Within a year, the Board raised $100,000 to launch the program, further demonstrating the profound degree of interest in the community for a Catholic Montessori program. In August 1998, Queen of Angels Montessori School (later renamed The Good Shepherd Catholic Montessori) opened its doors in leased space in Newtown, Ohio, with 28 preschool and kindergarten students. Since that time, we have maintained our business plan to expand one grade level per year, and currently serve 200 students from preschool through eighth grade. In 2002, we moved to our present location just north of Mariemont, Ohio.

The Good Shepherd Catholic Montessori (GSCM) is a non-profit, independent school that is fully licensed and chartered by the Ohio Department of Education. As a private, independent school, GSCM does not receive a parish subsidy or funding from the Archdiocese.
