i spent over a year researching options for my two children and finally decided on Columbia Montessori School. The school is WONDERFUL! I can't say enough about the teachers. My kids are 7 and 4 1/2, and both started at 2 1/2 there. My 7 yr old is reading at a 3rd grade level already b/c of the great foundation she had there.
My niece, nephew and neighbors have go there too b/c of the recommendation. The school administrator is Maria Garcia and you can let her know that the Wong family referred you. Their website is:
