About

For over three decades, ROI Design has redefined what business-focused interior design can achieve. Founded in 1993 in Grand Rapids, we’ve built our reputation on a simple yet powerful premise: great design should work as hard as you do.

Beautiful spaces should do more than inspire—they should perform. At ROI Design, we create environments that strengthen operations, elevate culture, and deliver measurable returns. We’re strategic partners who understand the powerful connection between space and business success, transforming your vision into high-performing environments through intentional, precise design.

Mary founded ROI Design in 1993 as Designers Workshop with the principle of providing design services as an investment focused on creating lasting customer experiences. Under her leadership, the company completed hundreds of design and furniture projects, specializing in workplace strategy and design, medical and dental offices, industrial and manufacturing offices, and multifamily spaces. Throughout her career, Witte earned recognition from clients and the community who consistently described ROI Design as “good businesspeople” – a reputation she took particular pride in.
