I have three children attending St. Gertrude. Been a happy member of this community for 7 years now. My children love their teachers. I personally love the small, community environment. My kiddos feel safe and seen. I know they're safe and well cared for. Academically, all three have excelled. Emotionally, and socially, they've thrived. I couldn't ask for more. Best decision we could have made to bring our kids to this school. You really get what you put into it. Our experience is biased. We are those overly - available parents willing to commit to the hours of service, and consistent with the parent-involvement expectations. Highly recommend it.
