My neighbors send their four children to Adelphi Academy and I have heard nothing but good things from them. Exciting events are always held at the school plays, art exhibits, academic ceremonies, etc. and the families are always included. My own children are grown now, but if they were still of age, I would definitely send them to Adelphi.

Adelphi's Theater Arts Program is incredible! The students work very hard when it comes to the productions and events that we have at Adelphi. We are currently working on our holiday brunch performance, which features an original Happy Holiday Musical Revue! I am so proud of the students and staff who work together to make our performances look and feel like professional theatrical productions!
