Taking my son, Nathan to Prime Foundation Montessori is the best decision I have made concerning his academics. PFM has the best teacher I have ever met! To say she's amazing is putting it mildly! My son Nathan is now literally a genius! He went from knowing just 1 to 10 to knowing 1- thousands and not just reciting but understanding the quantities and symbol as Ms. Osato would always say. Nathan now knows how to carry out the four operations, not just the basic but also exchanging. He can now work with Addition, Subtraction, Multiplication and Division at 4 years old! He clearly understands place value and the dynamics of carrying over and exchanging in all four mathematical operations. He understands the decimal system almost perfectly, I wish I could say perfectly! Nathan looks forward to seeing his teacher and coming to his classroom at PFM everyday! He really loves his school! You need to see how his eyes light up when he talks about his day at PFM plus he is never ready to leave school when we go pick him up! Thank you so much Prime Foundation Montessori. I wish I can say it in better words. I brought you a timid and academically struggling boy, who didn't like math. You gave me a bright, smart, intelligent son. You made him a mathematics star in such a short while at Prime Foundation Montessori! Nathan is now so in love with Math! I am overwhelmed with so much joy.

I made the decision to change my son's preschool as It was recommended by an Occupational Therapist, since my son was having some difficulties with movement, anxiety and attention at his previous preschool. I took my son to Prime Foundation Montessori. After attending Prime Foundation Montessori preschool program for only 2 months, my son is already a different boy. Their Montessori Environment has helped him with his desire to move around the classroom and work in a calm, peaceful manner. It has helped to build his attention span through their activities and lessons, but most importantly it has helped him learn social skills and discipline. I never thought I would hear him ask, "Dad, Is it time for school? I want to go to school." He has built a strong community relationship with his peers and teacher and he truly enjoys the freedom of choosing the lessons he will work with as he progresses with the classroom material. I specially have appreciated working side by side with, Ms.Osato to help learn alternatives in coping with my son's learning difficulties. I have also enjoyed working with Ms. Osato in learning more about the Montessori philosophy and how I, as a parent, can help my son reach his highest potential by following the same approach and philosophy at home. Saying I am grateful to Prime Foundation Montessori can never be enough. You have given my son so much and I am so glad we found your Montessori preschool.
