Over the least 7 years, we've watched as our son grow creatively, socially and academically in the nurturing OSMS community. The faculty and staff are caring, intelligent individuals that support, challenge and grow the kids in every way. I'm looking forward to what the next three-year cycle will bring in Upper Elementary.In short, we love it!
