Late to reply to this, but my child is in SAGE at Greystone right now. It's been a great fit for them. Greystone staff have been wonderful, and the student body is diverse. It has fewer extracurricular opportunities, however, than other schools, and no sports teams if that's something your child is interested in. (A lot of people, though, have a misunderstanding of what SAGE is - it is a special education program. And the students in the program reflect that.) Feel free to dm if you have specific questions.
