According to a blog dedicated to reviews of Waldorf Schools in different cities, the Waldorf School of Saratoga Springs has been touched by NXIVM for years.
From the blog:
Second; Coincidentally someone who is close to me and that I care deeply about asked me what I thought about the school because her granddaughter was thinking of going to their preschool.
Before NXIVM was done with her, she had lost her husband, who was forced to defend himself against ridiculous NXIVM Black Ops allegations, her piece of mind and the respect of the community. So why am I bringing this up? DeeDee at least on the Waldorf School website is still listed as a high school teacher, although she is the only staff member not to have biographical information available.
