I highly recommend Sutter Peak!
Providing the Work Sample packets ahead of time is very Pro-Parent! We really appreciate it!
I have had the best experience at Sutter Peak for my first official year of homeschooling! I love getting to customize lessons for both of my children (who have very different needs). I love that my children get more one on one time in a single day than they would get in an entire week in a public school classroom!
