J.P. Cullen & Sons, Inc.

JP Cullen is a fifth-generation family-owned business. For over 125 years we have taken on the most challenging government, education, healthcare, commerce, industrial, arts & entertainment and historic restoration projects across Wisconsin, Illinois, and Iowa.

Today we are over a $400 million full-service pre-construction and construction company with 600 employees, managing projects from $1,000 to over $80 million in size – from new construction (office buildings, university buildings, residence halls) to additions and renovations (healthcare facilities, K-12 schools, industrial plants) to self-performed work (e.g. steel erection, masonry, carpentry, concrete, historical restoration, equipment installation).
Our corporate headquarters is located in Janesville, Wisconsin. We have a Milwaukee office in Brookfield, Wisconsin and an office in Madison, Wisconsin.
