Founded in 1931, Trinity UMC was originally named the East Gary United Evangelical Brethren Church and started with 22 members in the East Gary/Lake Station area. With growing membership, they soon outgrew their worship space. 

          The current building on the north side of Hobart- 3561 Randolph St- was started in April 1958 with the first Worship Service held on January 3, 1960. 

​          In 1968, the United Evangelical Brethren merged with the Methodist Church becoming Trinity United Methodist Church.
