Trinity School was such an amazing place for my 3 children. They learned to be confident public speakers, wrote at a high school level in middle school, learned organizational skills, and were completely prepared for high school. The teachers are caring and really help the students. The community at Trinity was the BEST!

Trinity was the best choice for our child. The size of the class and the attention to our child's needs in the caring and nurturing environment made for an excellent experience.

I didn't realize how well Trinity School prepared my children for high school until they became freshman. Compared to their peers, they found themselves far better prepared when it came to academics, organizational skills, time management and overall confidence in themselves. They were often complemented to their high level writing skills. I cannot recommend Trinity School enough - it was the perfect combination of a small private school that gave my children the one-on-one attention they needed academically while still providing them a faith-based education. They friendships they developed will last a lifetime.
