In addition to all real Yelp reviews I can add that after dealing with Big City Montessori our family became the victim of the money extortion scheme. Our son was terminated from the school after a little over a month. After refusing to work with the child the school management decided that its easier for them just to get rid of our son. The professionalism of this organization was questioned in many previous reviews. Id like to write about something else - the money extortion using the system loophole.We ended up paying close to $5K for one month of service. We paid $2K deposit and fees, $3.8K for the next 2 months. After termination we were refunded only $780. It appears that even though our child was kicked out of the school we were charged the additional 15 days for the gracious period. Conducting business in such manner should be simply illegal. Beware of these scumbags.UPDATE: After we made some noise the BCM management decided to return us 1.4K of the non-refundable deposit. We still ended up paying around 3.5K for one month. Overall the experience with this organization was negative.
