I am a parent of two kids at All Saints. Our experience with it has been great. I am sorry if others think of it as elitist, but I haven't found that to be the case at all. Like anything else in life, it is what you make of it. Many of my best friends in the past few years have been made thru this school with parents of other kids. I think your kids will have a great experience.
For the record, I don't thumb my nose at anyone...never have...never will. An ounce of pretention is worth a pound of manure...so is making judgement about people you don't really know.
