There are a few very small girls' schools in the area (Oldfields and St Timothys). I wouldn't really compare them to Nora but might be worth a look if the child is a girl? Both are really warm communities where the girls get a lot of individual support.

Not really. RPCS or Boys Latin could potentially be a fit depending on the specifics. There are more K-8 options, but since Nora is the comparison, I'm assuming you are asking about high school. Lab or Harbour potentially, but probably overkill if academics don't need significant support. Glenwood Academy might be worth looking at (not in Baltimore but there are definitely families that make the drive). Fusion Academy can work well for kids with anxiety, but it is quite expensive.

Friend’s child is struggling and I’m wondering if there’s a comparable option for kids with severe anxiety.
