This is a fantastic school. Our son has thrived emotionally and academically. He just loves going to school and has made lots of close friends. The teachers are kind, empathetic and pay very close attention to the children. We couldn''t be happier.

We have been absolutely delighted with our son''s experience here. The school offers an incredibly diverse array of learning experiences - academic, cultural, physical, musical, artistic - and a safe environment for forming early friendships. The teachers are wonderfully kind, patient, and supportive Cannot recommend highly enough!!!

We''ve had our kids at this school for several years now (overlapping) and have been very pleased with the school, the community, and the development of our children.

It's been a year since our son has attended BCMS and we couldn't be happier with the leaps in his growth & development. As a 3.5 year old, he has good fine motor skills (drawing & writing), is able to focus for long periods of time (completes 100-piece puzzles on his own), and is starting to read & write simple words -- much of this is because of BCMS's montessori style of teaching & structured program. The teachers are experienced, loving, calm, and helpful; the adult to child ratio is 6-8:1. We very much appreciate how CLEAN the facility is, and the space is just beautiful & enriching, indoors & outside in the playground area. There is music, art, and spanish enrichment programs every week, and even on-site field trips that allow my son to learn hands-on about things from wildlife to different cultures & holidays. Lastly, they have an onsite kitchen with freshly prepared hot lunches everyday.
