Always Evolving

LANGE grew from real estate roots. Jeff Lange gained his real estate license in 1981 and founded his first company. Though it didn’t turn a profit in its early stages, Jeff persevered, drawing on his Midwest determination and work ethic to grow his business.

Today, LANGE is a family of companies with many branches—and Jeff’s trailblazing spirit guides them all.
