I've always felt very welcome at the school. The admin staff are very friendly and I've happily volunteered my time in the school over the years. It's a great way to get to know the staff, teachers and kids. As people come from all over the city, I don't know all the parents in my daughter's class. But my daughter has play dates with her friends and I know parents who live close by.
The staff and teachers have been incredibly welcoming and responsive to any concerns. Hudson does not have an active parent or structured social network for parents. The good thing is you are not being bombarded with events and continually asked to raise funds. The downside is we don't have much interaction other that with our children's friends parents.
