“I went to school there until I graduated and it was great! The teachers really took their time to help their students in any way they could.. I learned not only what I needed to learn for the core curriculum but I also gained a lot for my Muslim identity. I was very prepared for college and what it took for higher education. I have great memories there and still have amazing relationships with the teachers and students. I look forward to the things that Mercy does in the future.”
