About Us

Tertium is a private real estate investment and development firm dedicated to shaping lifestyle-driven, community-centered projects in our home of Dubuque, Iowa, and across the broader Midwest. Specializing in all facets of real estate, we focus on investments, ground-up development, historic properties, adaptive reuse, tax incentives, value-boosting asset management, property repositioning, and operations refinement.

At Tertium, we create lasting returns by bringing a community-first approach and exceptional design to spaces that have often been overlooked or undervalued by conventional investment firms. Our leadership team brings over 40 years of collective experience in the real estate industry.

Guided by the mission to reinvent lifestyle hospitality through thoughtfully crafted spaces, we build environments that foster emotional connections and serve as backdrops for meaningful life experiences. Each project is designed with the purpose of enriching the community and elevating the way people live, work, and play.
