JLG Architects

    OverviewSuggest Edit

    For 27 years, JLG has worked hard to make life better for our families, co-workers, clients, and communities. From what was once a three-person design studio by Gary Johnson and Lonnie Laffen has grown to become the fastest-growing architecture firm in America, according to Inc. Magazine, and the 19 firm in business, according to Architect Magazine. We have had the great honor to work with thousands of the most engaged and frankly, totally awesome, clients and communities in the Midwest, including 60 college campuses and some of the largest healthcare providers in the world. We recently turned the keys to the firm over to our staff and become 100% Employee-Owned. Because the best place to work – for this generation and the next – is the one you own.
