I was hesitant to send my daughter here for financial reasons but I am so glad we attended both a Preview Day and Open House. Financial aid is definitely accessible if you qualify and almost 50% of their students receive financial assistance. The teachers care about the students and want them to succeed. The College Counseling exceeded my expectations in preparing my daughter for her future. I expected a lot for a private school and it went above and beyond my expectations.

My experience at Carondelet has been very positive. The school and teachers have encouraged and helped me to reach my full potential in all parts of my life. Specifically in a leadership role, I have learned how to be a well rounded and encouraging leader to help support all of my peers.

Being able to join Carondelet has been such a privilege. From being greeted by members of staff and teachers in the hallways to going into every classroom ready for a new day is also so fun and educational at Carondelet. My teachers since the start of my freshmen year have been very kind to me. They make it a habit to check in on me every day and always have a bubbly personality. Teachers make class days for me fun even when I don't have the energies to learn. Every lesson is never boring and I actually enjoy engaging in lessons. Even on my worst days being at Carondelet has brightened my days. Not only have the teachers been kind but just the community in general. The girls are very kind and welcoming. I look forward to coming to school every day.

Carondelet is the phoniest place I have ever seen. They claim to have a catholic message when in reality all they care about is money. They do not care about the well being of your daughter, but rather how much is in their pocketbook. I may sound bitter, but I'm just being brutally honest. This scho...

Going to Carondelet is probably the best thing that has ever happened to be. I feel very loved and safe every time I walk onto campus. The sisterhood is a real thing and you can feel it every where you go. The faculty and administration truly care about their students in and out of the classroom. Ca...

I think had I had the opportunity to make the decision all over again....I would not have chosen Carondelet for my daughter. Here's why....I think I was thinking that she could escape some of the drama of adolescence here...she has not. I thought that the quality of education and athletic opportunit...
