“Giving students the tools for learning the truth, training their minds in the search for truth, and showing them that a life lived without the truth is a life less than human–these are all fundamental to educating students for a life befitting beings made in the image and likeness of God.”


Experienced leadership is essential to providing your child with a quality education. Trinity School at Greenlawn’s national and local leadership team has nearly 100 years of experience working with students and families like yours.
