Senior Vice President

MWH Constructors, Inc. (MWH) is a leading national water- and wastewater-treatment-focused general contractor with experience in both municipal and industrial applications. Our legacy, which traces back to 1820, is built on the expertise of some of the water and wastewater industry’s leading innovators and our deep roots as hands-on builders. We are committed to providing exceptional value through a comprehensive suite of services from preconstruction and digital delivery through hands-on construction expertise and commissioning and startup. While we are experienced in traditional design-bid-build projects, our true expertise shines in collaborative delivery models such as construction management at-risk (CMAR) and design-build (DB). This collaborative approach allows our multidisciplinary team of construction professionals and skilled craft to work closely with clients, providing streamlined, high-value solutions that meet project goals. We are proud to operate alongside our regional subsidiaries, Slayden in the Pacific Northwest and Methuen Construction in New England, expanding our reach and reinforcing our commitment to “building a better world” one project at a time.
