I am a local homeschooling mom. In all my dealings with hundreds of Sac local plus many many state wide hs families I continuously hear of Waldorf and Montessori schools as parents talk about alternative methods they have tried and respect.
But a few years ago I ran across our own local Sudbury school. Which in some ways closely aligns with an off shoot if you will of hs called unschooling.

If this fascinates you or better yet you are a local homeschooler I look forward to hearing from you.

Take care
