What Our Families Are Saying…

  • Tess and Manuel Florez, Parents of Jesse and Sierra (Kindergarten Class of 2010-2011)

    We’ve had our twins at Calaveras Montessori, and then here at Crescent Montessori since the age of 2 ½ years old. They’re now 5 ½ and currently attend Kindergarten here. In the beginning our son was “wild” to say the least, but the structure along with allowing him to learn and do things at his own pace has greatly calmed him down and facilitated a sense of order to his previously chaotic method of learning and doing things. As for our daughter, she has just flourished because she is allowed to do things on her own and go at her own pace. She is not held back and she is given the opportunity to soar ahead without feeling pressured to slow down or stop. Like most parents we did struggle somewhat in the decision of taking them out of Crescent and put them in the public school for Kindergarten. We decided we wanted them to complete their third year in the classroom and give the chance to be the “big kids” of the school. They greatly benefitted from the experiences and rewards that came with being the kindergarteners. If we had to do it all over again, we wouldn’t change a thing. We’ve been amazed by how much our children have learned and what they know compared to other Kindergarteners we know and come into contact with, not only academically but also in practical life and social skills. We highly recommend keeping your child/ children at Crescent for Kindergarten. This environment has been crucial to our children’s success and development.

    An incredible learning environment” “Calaveras has been an incredible learning environment for my children. They have not only grown academically, they have also gained important social and leadership skills. It’s wonderful to see how they approach new problems with confidence and creativity.

  • Joanna – mother of Sasha and Talia

    Calaveras’s low student-to-teacher ratios, along with the flexibility and skill of the teachers, have allowed each of my children to flourish, even though they have different personalities and learning styles. I’m convinced that Calaveras gives them the solid foundation they’ll need to be successful in their future endeavors.

Patricia Cordeiro

Head of School

Patricia “Pat” Cordeiro started her career in education after graduating from the University of Singapore with a BA in Arts and Social Sciences. She went on to obtain a Diploma in Education from the Institute of Education. After teaching Language Arts and Literature for 7 years, she obtained her Montessori training in London in 1985.

Pat was led to Montessori from the desire to create an environment of self-discovery for her students, and recognized the stress and challenges in the traditional education system. She became deeply inspired by Maria Montessori’s child-centered approach to learning which convinced her that her true calling was to work with preschoolers.

In 1991, together with 6 mothers and their children, Pat started a Montessori class in her apartment for her 2 ½ year old daughter. This marked the beginning of P&J (Pat & Julie) Kindergarten, a Montessori school she founded with her friend. She directed the school until 1997 when she moved to California, however the school continues to thrive in Singapore.

Pat is now the Head of School at Calaveras Montessori School. She is excited to run a school again after spending many years in the classroom. In her spare time she spends time with her children and husband.
