What Our Families Are Saying…

John Family

Mendoza Family

  • T. mother to 4 year old girl

    Our daughter has been attending Main Street Montessori for a little over a year now. She enjoys going to school each day and seeing her teachers and classmates. We often find her happily singing new songs she learns from class, and she tries to teach us as if she is the teacher. She especially loves the new after- hours art studio and cooking/gardening studio sessions.

  • MV mother to 3.5 year old boy

    My son started at Main Street Montessori when he barely turned three. He is currently three and a half years old, and in the matter of a few months I could see him grow more in so many ways. I notice his independence increase, his vocabulary exploded, and love for learning seems limitless. The teachers are professional, knowledgeable, caring and nurturing, I trust them every day to guide him to be the best he could be socially, emotionally, and academically, yet most importantly as a unique individual. Their connection with my son is warm. He loves coming to school, it’s like a second home for him. I couldn’t ask for a better place for my son to grow, learn and thrive. From the bottom of my heart, thank you.

  • Parent

    My daughter has been going to Main Street Montessori since she was 3 years old. She’s five now, and we couldn’t be happier with our decision to start her off in MSM after we moved here from Virginia

  • Parent

    My daughter has really blossomed over the last 2.5 years at MSM. From a shy child, she’s grown into a confident little girl. To start with, the atmosphere in the school is very welcoming and joyous. I have never seen a child crying while coming into class. At the age of 2.5 – 3, this mattered a lot me, to create a positive impression about school and MSM succeeded in doing that.

  • GS mother to 5 year old girl

    I am very happy with the teaching methods, which focuses on concepts rather than rote learning. The teachers have always been very responsive to questions and concerns. The director, it is evident, herself believes strongly in the Montessori Method and that passion comes through in the work everyone in the school does. It’s a balanced curriculum with arts, dance, cooking, gardening, in addition to academics. A special mention about the kindergarten program – my daughter is proud to be a kindergartner and I can see why. At 5, she can read chapter books, write stories, do basic multiplication and has even started cursive writing. I couldn’t have asked for more.

  • Parent

    Choosing a school for your kid is never easy and as part of our search we looked at many aspects of schooling for our child and surprisingly Main Street Montessori came back on top in every list. So with a sense of cautious optimism that comes along with sending your kid to school for the first time, we sent our son to Main Street Montessori. And one year on we are glad that we did!

  • SA mother to 4.5 year old boy

    The atmosphere in the school is clean, pleasant and inviting with a very caring and engaging staff, truly they put children first always. We are very thankful to the Teachers and staff at Main Street Montessori

Sarah Jeremiah

Assistant Head of School

Ms. Sarah J. is the Assistant Head of School at Main Street Montessori School.

She was born in Singapore, and moved to Fremont, California when she was 10 years old. While in Singapore, she had the privilege of being a part of the pioneer Kindergarten class at P & J Montessori School; which continues to thrive today.

After graduating from Irvington High School, she attended the University of California Santa Cruz where she majored in Film & Digital Media. Throughout her high school and college career she enjoyed spending her summers working with children through her church community as well as other outdoor camp programs.

Prior to joining the Montessori School of Silicon Valley, she worked as a program manager at a tech company. However, after almost 5 years in the fast paced tech world, she wanted a change of pace. She first heard of MSOSV after a friend asked if she would work one-on-one with their child who was attending Calaveras Montessori. After a few months of being in the classroom full time, she learned that although she enjoyed working with the children, her strength was in administration.

She enjoys learning more about the Montessori philosophy as an adult after having been a Montessori child!
