How to Apply

Please complete our brief interest form here. 

We will follow up with you by phone or email.

To be eligible your child must be at least 2 years and 9 months of age by the first day of school.  (If your child turns 2.9 during the school year and if there is an opening available at that time, we will accept them).  Vaccinations are required and religious exemptions are not accepted.


There are currently no openings for the 2020-21 school-year.  Registration for the 2021-22 school year opens January 25.  Morning spots for 2 and 3 days/week are limited.  If your child is ages 4-6 and does not nap, we recommend afternoons.  If you live in Chestnut Hill, Brookline, or another neighborhood between the Arboretum and Wellesley (MassHort) we recommend our Wellesley program.

We look forward to meeting you!
