Both Montgomery County and City of Rockville camps provide additional staffing for ADA accommodations. They had a counselor who was with my son and helped him take extra breaks, go to less overwhelming spots and were great. There was no additional cost.

Holton Arms Creative Summer was good for us. Kids 2nd and up pick five ‘classes’ and it’s easy to avoid sports and swim. Our older NT kid went so we knew what classes to guide our younger towards choosing. Ended up with painting, photography, reading for fun, ballet, and newspaper.

Admittedly class transitions were hard for the first week, but not a problem after that.

There's a few in Rockville. Alliance pediatrics has one. Forget the name but there's a center that does this sort of thing that I've heard great things about, especially for anxiety. A lot of practices offer summer groups that can help.

I’m looking for a summer day camp in Montgomery County that will suit my rising 3rd grader with sensory processing challenges, anxiety and adhd. Any programs that are good with supporting anxious and/or neurodivergent kids, whether that’s their specialty or not?

The biggest stressors at other camps have been gym activities (prolonged periods of loud noises in an echoing space) and pool days (bus rides with lots of movement and noise, wet suits, hot to cold transition).
Even a week program or half day programs would work for us. Thanks for any ideas you can share!
