Children & Youth Ministries

Jesus loves children and so do we! We believe that from the youngest infant to our teens, all should experience the love of Jesus and begin to know and live out his purpose for their lives. At Holy Trinity, our family ministry team is dedicated to age appropriate curriculums and activities to foster love and followership to Jesus. Our skilled and caring leaders endeavor to build genuine relationships with children and parents in a peaceful, thoughtful, and safe environment for each to thrive. As we follow the seasonal church year, we are committed to teaching God’s word and understanding God’s sacraments.


Our classrooms are marked by an atmosphere of peace and playfulness. Through a posture of hospitality, our leaders invite participation in activities and ensure each child feels safe and loved.


We do not settle for merely teaching Bible facts and data. We utilize Scripture to introduce children and youth to a way of being in the world as followers of Jesus. Our aim is to encourage growth in “wisdom and stature and in favor with God and others” (Luke 2:52). We cultivate formational practices to teach children and youth how to “turn their ears toward wisdom” and “store up God’s commands” in their hearts, in order to apply God’s word to their daily lives (Proverbs 2:1-5). Our youth leaders are intent on building relationships and connecting students to God through word and prayer. Youth are encouraged to develop friendships with one another through wholesome, fun outings.


At Holy Trinity Church, your child’s safety is our priority. We have a “team teacher” policy which is a team of two or more adults present to lead and supervise children and youth. Our childcare workers, leaders, volunteers and staff undergo safety protocols including training, fingerprinting and background checks. First-aid emergency kits are present in each classroom. Our leaders ensure safety guidelines are followed each Sunday.

Prayer & Care Ministries

At Holy Trinity, our intent is to serve with the same heart as our Lord’s, with compassionate and attentive care. Our desire is to assist people with various needs so that they may encounter God’s love. Pastoral care ministries at Holy Trinity Church include: biblical and pastoral counseling; spiritual direction; prayer, benevolence, and visitation.


Holy Trinity Church has trained and compassionate prayer ministers available during and after the worship service to pray with you.
