St. Theresa is a really great school! They have the most caring teachers and administration. They really do care about me and my kids. St. Theresa is a warm and welcoming community. They go out of the way to include all families. Their academics are tops. My kids were very prepared for Dowling Catholic High School. They have done very well there because St. Theresa prepared them so well for the high level of academics that Dowling demands. Because of this my students have received big scholarship offers to colleges because they did so well and were so prepared for Dowling as freshman. I have an 8th grader that will go on to Dowling next year and is very interested in taking the higher level math and science/engineering courses at Dowling because of all that he learned through the STEM program at St. Theresa's. This program really engaged my kid. I just didn't find this in any other school. St. Theresa is an excellent school.

St. Theresa's Catholic School is a fantastic school. We have 2 children that we send there. There are a number of Catholic schools that are much closer to us yet we still send our children here. The individual attention, small class size, excellent teachers and wonderful community of parents made our decision easy when deciding where to send our children. We could not be more pleased with St. Theresa's, it is an excellent school.
