About
Colleen Horner owns and serves as president of Horner Plumbing, the Pewaukee residential and commercial plumbing contractor brothers Bruce and Jim Horner started in 1969.
After Bruce’s death she took the presidency, keeping the women-owned family firm on the values the founders set—quality, honesty and integrity—while sons Chris and Patrick moved into operations and construction management.
The company grew from a south-side Milwaukee kitchen-table dispatch into a Pewaukee campus with a two-story public showroom and the Colleen Horner Design Studio remodeling arm. Work now spans new-home plumbing, remodeling and commercial projects in healthcare, education, hospitality and multifamily housing across southeastern Wisconsin.
Wisconsin AEC coverage identifies Horner Plumbing as a certified Women-Owned Business Enterprise and credits Chris with day-to-day leadership alongside Patrick while Colleen remains owner and president. That owner-of-record status, WBE certification and half-century Lake Country footprint make her the equity principal for this family contractor story.
