In the world of commercial construction, few names carry as much respect and longevity as Western Partitions Inc. Headquartered in Wilsonville, Ore., the company has been a cornerstone of the Pacific Northwest’s building industry for more than half a century. Under the guidance of Chairman Mike Roach, WPI has grown from a family-run drywall operation into one of the largest and most diversified specialty contractors in the western United States.

 Founded 53 years ago, WPI specializes in drywall, acoustical ceilings, steel stud framing, insulation, plaster, fireproofing, doors, and prefabricated wall panels. Today, leadership has transitioned to the next generation: Victor Roach serves as president, and Angela Roach as vice president. The family legacy continues to expand, with third-generation members Griffin Roach and Hailey Palmore joining the company.

 “We’ve always believed in giving our employees opportunities to grow with the company,” Mike Roach says. “The longevity of our team members tells that story better than anything—some have been with us for over 30 years and are now stockholders.”

From Apprenticeship to Industry Leadership

 Mike Roach’s path into construction began humbly. “My cousins, aunt, and uncle had a drywall company, and I went to work there as an apprentice in 1967,” he recalls. That early experience laid the foundation for a lifelong career defined by hard work, craftsmanship, and innovation.

 Over the years, WPI joined leading industry associations including SWACCA, AGC PRIDE, WWCCA, AWCC, NWCCA, WACA, WCCG, AWCI, Associated General Contractors and the Northwest Wall and Ceiling Bureau. These partnerships have helped the company remain at the forefront of industry standards, safety practices, and new technologies.

 One project that captures WPI’s technical mastery and creative problem-solving is the Alta Art Tower, a 21-story apartment building adjacent to Portland’s Artists Repertory Theatre.

 Through a design-assist process, WPI’s in-house design professionals developed a method to prefabricate the building’s exterior wall panels, including pre-cladding with a brick rainscreen system. The result? Once panels were installed, the building’s exterior envelope was immediately water-tight—a major achievement in both efficiency and design quality.

 “We had about 40 percent of the 914 panels ready before installation began,” Roach explains. “It allowed us to maintain an incredible pace while delivering an exterior finish that elevated prefabrication to a new level.”

 The project, completed in collaboration with Ankrom-Moison Architects, Anderson Construction, and Wood Partners, solidified WPI’s reputation as a leader in prefabricated exterior systems. The success also expanded WPI’s expertise in delivering turnkey scopes, including interior framing, insulation, drywall, ceilings, firestopping, acoustic wall panels, and stucco finishes.

Craftsmanship Meets Technology

 At the heart of WPI’s innovation lies its prefab facility, where engineers and craftsmen work together to design, fabricate, and assemble panels before they ever reach the jobsite. The team’s use of advanced materials, including the Corium Thin Brick rainscreen system from Germany, reflects Roach’s enthusiasm for technology that blends aesthetic beauty with practical performance.

 “The Corium system really impressed us—it gives a clean, polished brick look while improving installation efficiency,” he says.

 WPI partners with many of the industry’s leading manufacturers, including USG, CWallA, Armstrong World Industries, CertainTeed, L&W Supply, FBM and GTS.

 Despite recent slowdowns in Oregon and Washington, WPI continues to find growth in other regions. Roach acknowledges that “some areas are doing better than others,” but diversification remains a central strategy.

 “When hard times hit next, we’ll continue to diversify—focusing on high-tech, higher education, and hospital projects,” he says.

 This adaptability has allowed WPI to weather industry cycles while maintaining its people-first culture. “We focus on private works projects instead of public ones,” Roach explains. “It allows us to be more selective and maintain our standards of quality.”

Family, Teamwork and Legacy

 For Roach, business success is inseparable from personal values. “Our greatest achievement as a company is giving employees opportunities to grow,” he reflects. With a workforce of 1,500 employees, that commitment extends across every department and jobsite.

 His passion for work is matched by a few personal interests—music, football, and hunting—and an appreciation for history and leadership. Asked who he’d most like to have dinner with, Roach names George Washington or Ulysses S. Grant, two figures who led with courage and conviction. His favorite book, Ken Follett’s “Pillars of the Earth,” fittingly tells the story of builders and visionaries whose work stands the test of time.

 As WPI looks to the future, its blend of innovation, craftsmanship, and family leadership positions it well for continued success. With new generations stepping up, the company’s legacy is secure, but its ambition remains firmly forward-looking.

 “We’ve been given opportunities to grow in new areas,” says Roach. “That helps our younger employees move up and keeps WPI strong for the future.”

 From drywall beginnings to 21-story architectural landmarks, Western Partitions Inc. stands as a testament to what’s possible when family, innovation, and dedication come together to build something that truly lasts.
