School Reviews

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.
