“The Secret of good teaching is to regard the child’s intelligence as a fertile field in which seeds may be sown, to grow under the heat of flaming imagination.” – Maria Montessori



Raife Cebeci, Head of Schools

After graduating from Law School at Istanbul University in 1991, Raife Cebeci moved to the U.S. with her husband. Her first child inspired her to make a change of career path, so, while raising three young children, she completed her master’s degree in Educational Psychology at the College of St. Rose in Albany, NY. During the course of her master’s program, she was introduced to the Montessori philosophy of education, and her love of Montessori was born. She later received her American Montessori Society (AMS) teacher certification from the Princeton Center for Teacher Education in New Jersey.

She opened her first school in Schenectady, New York and later moved with her family to the Philadelphia area, opening a second school there. She then set out to bring a new vision to life: International Montessori Schools (IMSchools), whose goal is to provide the highest quality of Montessori education to children of all cultures, faiths, and backgrounds. Shortly after starting the first location she and her husband partnered with another couple and close family friends. From 2004 to 2012 they opened five schools in Pennsylvania. In 2011, IMSchools acquired its sixth school in Wilmington, DE, which houses the Montessori Institute for Teacher Education (MITE). Since then, Raife has been the Executive Director of the program.

In 2014, she started traveling to her home country, Turkey, to guide the growth and spread of Montessori philosophy there, opening a state-of-the-art laboratory school and teacher training program. In 2017, the teacher training program became the first and only program in the country to be accredited by MACTE (Montessori Accreditation Council for Teacher Education) and affiliated with the AMS as the additional location of MITE. Raife directs and teaches at the summer intensive teacher training program there.

All the while, Raife has raised her five beautiful children according to the Montessori philosophy. She loves nature, traveling, and children.
