A Wisconsin native, Joe began his development career in 1985. Focusing on urban infill development, he is responsible for numerous projects throughout Madison and Dane County.

Joe launched his construction career in 1976 with the founding of Design Shelters, a custom home design company. While operating Design Shelters, Joe founded Krupp General Contractors, building a wealth of commercial offices, clinics, senior housing, restaurants, industrial and multi-family mixed-use projects.

Over the past thirty-five years Joe has been a primary developer of the Schenks-Atwood neighborhood, revitalizing it into one of Madison's most desirable and walkable residential neighborhoods.
