Service is a key component of a Holy Trinity Education. Not only is it an important part of a college application but, most importantly, it is absolutely necessary in the life of a Christian and in the formation of virtue, character, and leadership. Christ modeled leadership by serving others, and so the Christian Leaders of Holy Trinity model Christ by serving others as well.

All students are required to perform and document service hours every year. Freshmen are required to submit 20 service hours, and all other students are required to submit 30 service hours. 

In addition to these hours, the members of the senior class travel off-campus in their final semester to serve various organizations and institutions in the community.
