ABOUT TSP

TSP Collaboration

YOUR TRUSTED ADVISOR

At TSP, we believe great design starts with listening. We’re a multidisciplinary service leader with architecture, engineering, planning, and interior-design expertise all within a single company. What began as a one-man shop in 1930 has grown into a regional practice. TSP team members believe so strongly in our firm that we adopted a majority employee stock ownership plan (ESOP) to allow all team members a path to become shareholders. As employee-owners, we approach every project like it’s our own. It’s part of why each project is so much more than a building to us: We’re forging lasting relationships alongside the projects we co-create with clients.

Team TSP is passionate about beautifully functional designs that meet needs today and are flexible enough to have a meaningful purpose well into the future. We possess deep knowledge in education, community, and healthcare/wellness projects, including each market’s unique expectations and regulations. Pairing our diverse project background with strategic, fresh design-thinking enables us to shape legacy buildings across the Midwest.
