We started both my children at Montessori One when they were 2 years old, and we have had a wonderful experience. Our son had a difficult time with the adjustment, but his teacher took great care of him and paid special attention to him until he was adjusted and more independent. Our daughter adjusted almost right away since her older brother was there. It is amazing how much our children have learned at Montessori One. Our son is 4.5 and is learning how to spell and do age appropriate math (counting by 10s, odd and even numbers, etc). and our 3 year old daughter can recognize all letters and sounds. The teachers are all very attentive to the children and spend 1 on 1 time with each kid to make sure they are getting love and attention they need, all while teaching them age appropriate material. The extra circular activities that are included with the tuition are music and Spanish. Our children absolutely ADORE the music teacher and are learning about all different types and genres of music (who knew toddlers could learn so much about Mozart?) and the performance at the end of the year with the music teacher is SO CUTE! Our children come home reciting Spanish words and singing songs in Spanish. We love that they are being exposed to another language so early. Montessori One also has sports programs via Amazing Athletes and a tennis coach (not included in tuition but reasonably priced). Overall we have had a wonderful experience and Montessori One and think that are children are going to be very well prepared for TK and K.
