9/10GreatSchools RatingParent Rating AverageI cannot say enough great things about Holmes Elementary School. Both my kids have been through this school (one boy and one girl) and both have had equally excellent experiences. The principal and vice principal are engaged, proactive, and responsive. The student body are kind, caring, and supportive of their classmates. The staff and teachers are excellent and are a testament to the excellent school district that Darien, CT has invested in.I cannot imagine them having gone anywhere else and am so thrilled with their preparation for middle school.Parent Review3y ago
