Welcome to the Lake Union Headquarters

of the Seventh-day Adventist Church for the states surrounding Lake Michigan.

We serve huge metropolitan centers like Chicago, Detroit, Indianapolis and Milwaukee, but we also feel close to home in small cities and villages scattered throughout our mostly farmland territory. We serve almost 90,000 members in nearly 560 churches and companies in five local conferences. We are home to the Seventh-day Adventist Theological Seminary on the campus of Andrews University, AdventHealth Great Lakes facilities in Illinois and Wisconsin, as well as approximately 79 academies and elementary schools.
