When we were considering Lesley Ellis for preschool, we asked around on the playground, and just about every parent we talked to told us, "It's excellent! The only negative is the cost."
That matched our experience perfectly. The tuition is steep - though financial aid is available! - but everything else was fantastic, and we were consistently impressed with the teachers, curriculum, field trips, awareness of kids as individuals, interaction with administration, and more. My mom worked for decades in early childhood education, and (as an interested and involved grandparent) was also very impressed.
They welcomed/encouraged heavy parent involvement, from "come into the classroom to talk about something you're knowledgeable/passionate about" to occasional parent-meetups-over-coffee in the morning and more. But I was never, ever made to feel guilty about not being able to participate heavily, which was the norm once we had our second kid. (Who also went to LES for preschool, once old enough.)
We can't speak to their K-8 experience, but for preschool/pre-K/TK they were fantastic. read more
