  • What Friends of Trinity Are Saying

    I live in a suburb just north of NYC filled with million-dollar homes and successful people, and we pay stunningly-high school taxes. The elementary schools are good. But I can’t recall ever seeing test results that equal those in your Iowa Basics letter about the achievements of the kids at Trinity Academy. Congratulations for such a stunning, ongoing success.

    Trinity Academy provides an exemplary Catholic education for our children, helping them to grow ever more in Christ’s life and thus to find their true happiness.

  • What Parents are Saying

    It feels like Trinity is a hidden gem. Grace loves attending Trinity Academy! The small class sizes allow for individualized attention and kids to work at their own pace, and I love that she is learning how to pray and love Jesus in the classroom.

  • What Graduates are Saying

    Trinity Academy has greatly influenced my ability to achieve academic greatness and manage a busy school work load. This was important for me because, without the strong and steady academic life I had at Trinity, I would not be able to do the things I am doing now.

    -LT. Brendan Lee, Class of 2016

  • What Graduates are Saying

    Thank you is not enough to express my deep gratitude for the beauty, the wonder, the awe and the love you have given me during my education at Trinity. You changed my life completely. Thank you. Prayers for you, especially now in these challenging days, and May God bless you always!

    -Therese Moen O’Grady, Class of 2003

  • What Graduates are Saying

    Trinity Academy was a blessing in disguise when I transferred to my junior year. Over the next two years I learned numerous lessons about life and the Catholic faith that I continue to carry with me to this day. My time at Trinity will forever be a pivotal foundation of my teenage years.

    -Jourdan Reynolds, Class of 2010

  • What Students are Saying

    Last year was really a new experience for me. For the first time, my responses in discussions were given weight and listened to, my opinion was valued. Every bit of the school experience was new and unique.
