About GTMS:

Building blocks for a purposeful life

GTMS cultivates in children respect, confidence, autonomy and curiosity. A delight for discovery that our students carry with them for their whole lives.

Every choice we make, as parents and educators, is an opportunity to give each of our students the tools to make their own choices for learning and for life.

At Greene Towne, guided by our teaching staff, students discover for themselves a purposeful, active, personal learning journey, with unlimited potential to realize a wonderful future. Our classrooms are thoughtfully prepared spaces, designed to encourage and grow hands-on self-directed learning. Filled with educational materials that engage and spark thinking, where learning is structured around uninterrupted time, and exploration can take its natural course. Greene Towne students go on to lead fulfilling lives, because they have the skills to constantly build their own learning, and make their choices come to life.

Over 50 Years Growing With Philadelphia

Greene Towne opened in the fall of 1966 at Saint Clement’s Church, founded by parents with the goal to grow a “racially, religiously, and economically integrated school.” Greene Towne Montessori has been an integral part of the fabric of the Center City neighborhood we call home, fostering a carefully considered learning environment for Philadelphia’s children.

1966 September 14

Greene Towne School opens its doors to 25 students on the 3rd floor of St. Clements Church. For a small group of dedicated parents, it is the realization of a dream.Two founding parents, Portia Sperr and Maryanne Hunter, take the Montessori Early Childhood certification course at Ravenhill under Mother Isabel who brought Montessori training to Philadelphia while founding parents Kaki Kriebel and Jane Unkefer run the office.


Portia Sperr and Mary Anne Hunter leave Greene Towne to found The Please Touch Museum, based on the hands-on, experiential learning experience provided by the Montessori classroom environment.

Celebrating Curiosity in a Diverse Community

Our entire learning environment is thoughtfully prepared to encourage hands-on self-directed learning, structured around uninterrupted time, where exploration can take its natural course, in classrooms designed to prepare the children for the society they will inherit.

We continually celebrate differences in ability, sexual orientation and identity, social background, religious belief, and racial, national, and ethnic origin, because we see a diverse student body, faculty, administration, and Board of Trustees as an essential reflection of the Montessori vision and our place in the city of Philadelphia.
