  • Lead Pastor

    Mark Fuller

    Mark earned his Master of Divinity from Denver Seminary, his Master's in Engineering Science from Rensselaer Polytechnic Institute and his Bachelor's degree in Electrical Engineering from the University of Michigan. He and his wife Denise have three kids, and after over twenty years of kids in the house, they are enjoying an empty nest. While they were dating at U of M, he and Denise attended Trinity for a year. He never dreamed he'd end up as a pastor at the very same church. His favorite thing about Trinity he says is, "Grace". The people here have a spirit of generous grace that permeates how we love our community, how we welcome newcomers, how we interact with one another and how we love our pastors and staff. I thank God every day for the blessing of this church family."

He enjoys quality time outdoors (preferably in the mountains), laughs by his fire pit, and grilling fresh food with friends and family.

She has a Bachelor’s degree in Business from Alma College, and a Master’s degree in Business from Wayne State University. Sue has worked in accounting for many years.

She likes to sing in the choir, teach Sunday school, watch sports and spend time with family and friends. One of her favorite things about Trinity is experiencing the way God has been continually at work since it began to help people come alive with Jesus, grow with Jesus and change the world for Jesus.
