Our Team

Jim Ozier

Jim Ozier

In 1990, Jim Ozier followed the founder of a 7-year-old church, Trietsch Memorial UMC in Flower Mound, Texas. In his role as the second pastor for this young congregation, he learned first-hand how difficult the transition of pastoral leadership can be when a church has never done it before! When he left nearly 18 years later, the church had grown to more than 4,000 members and helped birth 3 new congregations. In addition, Jim saw how critical the “passing of the baton” is for the successor pastor following a long-tenured pastorate.
