I know for a fact there’s a Benjamin School in North Palm Beach.
We go by it all the time when visiting relatives.
That’s the primary school (and the former old entire school) - on US1. They also still have offices there.
They built a huge campus off Central Blvd. in Jupiter that’s been there for nearly 20 years now.
Benjamin School = Jack Nicklaus
He didn’t start it, but he made it great for his kids (some it worked on, some it didn’t).
