Eastern Ridge School on border of Great Falls/Vienna runs a reggio-inspired outdoor ed program.

We love the Reggio program at Beth El, but it's in Alexandria.

Our kids both went to Rodef Shalom in Falls Church (near Vienna). It's a Reggio program, and we all loved it.

Hi, I know its huge area we are keeping all our options open. We are evaluating the best childcare options with 3 kids.
1. Nanny for all 3 and 2 or 3 day program for our 2 yr old.
2. Daycare for all 3.

Here's a link with some Reggio inspired programs and others.

That's a huge area, OP. Are you looking for part time preschool or full day daycare?

we are moving to the area, still haven't decided on an exact location, we are looking anywhere between Fairfax,Vienna, DC or Bethesda. We are looking for a Reggio or similar play based program for our 2 yr old daughter and eventually our newborn twins.
