“Preparing Today’s Children to LEAP into Tomorrow’s Future”

Who we are

“LEAP” is an acronym for “Leaders Exploring Aspiring Promise”.   The Montessori Method educational pedagogy was created by Dr. Maria Montessori and her son, Mario Montessori who based her approach on scientific observations of children from birth to adulthood. Dr. Montessori was an Italian physician, educator, and innovator whose views focused on a child’s natural eagerness for knowledge. The basis of Montessori practice in the classroom is to respect individual choice of work, and uninterrupted concentration rather than whole group lessons led by an adult.

History of Montessori Schools

The Casa dei Bambini, or Children’s House was the first Montessori school that opened in San Lorenzo, Rome on January 6, 1907. Dr. Montessori’s learning materials and school’s success was acclaimed in Italy and spread to other regions. Dr. Montessori’s travels and writings gained her global recognition attracting many devotees. Her educational approach is widely supported with the development of more than 22,000 Montessori schools in up to 110 countries worldwide.

Benefits of Montessori Education

Many children at Montessori schools out-performed students who were in traditional educational settings according to findings by US psychologist across a range of compared abilities. Montessori teachers focus on personal development which produces more mature, creative, and socially adept children. The Montessori Method discourages traditional competitive measurements of achievement and concentrates on the individual progress of each child. With an emphasis on “practical life skills” children of different ages share the same classroom and are encouraged to collaborate and help one another.

My daughter is a current student in the primary part of LEAP Montessori School, she started at the beginning of 2017. She has been in Montessori style learning for 2years and has really thrived. She has adapted well here and really likes going to school, which makes everything easier. I really have a sense of security when my child is at this school. This school is clean, safe, well structured and a warm and welcoming environment. I haven't experienced a high turnover in staff and the teachers that are there are genuinely loved by the kiddos that attend including mine. I love the random text updates I get of my kiddos accomplishments with new lessons or having a great time on a field trip as well as if something doesn't seem right with her I get an instant text or call checking in with me. I would recommend this school as a great place for great learning and fun!

My son has been going to Leap since he was 18 months old (for nearly a year) and it has been the best experience for him! The owners, Betty and Sheila have been nothing short of wonderful; always being accommodating and understanding with us. The school and its staff have felt like a family to us from the very beginning. My son completely adores his teacher, Ms. Eloisa, and she returns that love and care to all of her students in the toddler room. Eloisa truly goes above and beyond with our son and all of the children. They learn something new every day, and teach the students real world application skills; we could not be happier with the school! As a bonus, the new location is perfectly set up, with a super cool room for the toddlers separate from the primary kids. The playground is huge and the kids get to spend a ton of time outside. We give them our highest review and recommendation :)
