About Us

Committed to Excellence

McKinstry Stauffer Yang Construction is a high-end residential and commercial construction company that has developed a reputation for excellence throughout the Pacific Northwest.

Over the past 40 years, we have remained committed to our values of honesty, integrity, and respect. We specialize in quality craftsmanship and the careful stewardship of our clients’ investment. From the first meeting to the final punch list, we love the challenge of each project, working with clients and changing people’s lives for the better. We are exceedingly vigilant in organizing and tracking the many decisions that are vital to the success of the project. Our goal is to always make the process engaging and enjoyable for everyone.

Many of our team members have design backgrounds, allowing us to work alongside architects and owners to collaborate with a strong collective knowledge in design execution. We can assist with design services or the process of recommending and selecting the appropriate architect or designer.


For over four decades, Joe McKinstry has led the way, set the tone, and built a culture of respect, stewardship, and success for the company. Working alongside Joe to maintain these values, owners Billy Stauffer and Wes Yang now lead the company into its fifth decade and beyond.

Joseph McKinstry
Founder and Owner

Joe, a third generation Seattle native, formed the Joseph McKinstry Construction Company (JMCC) in 1977. With a resume of successful projects that runs the gamut, from tiny bathroom remodels to rustic lodge retreats, the company’s award-winning work has spanned the geography and generations that make up the Pacific Northwest over the past 40 years. In 2017, Joe invited Billy Stauffer and Wes Yang to join JMCC as full partners and co-owners of the company.

Joe is committed to giving back to the community where he lives and works. He currently serves as construction advisor to Rainier Valley Food Bank as they build a new facility in the south end of Seattle. He is also on the Board of Directors for the UW Burke Museum and, in that capacity, serves as Co-Chair of its Diversity, Equity and Inclusion committee. Joe also served as President of Mt. Baker Community Club, and with his family volunteered with Habitat for Humanity Jimmy Carter Work Projects throughout the world (South Africa, Hungary, Haiti, Kentucky, New York, Eastside Seattle, and more.)

Billy Stauffer

Billy began his career in design and construction with a bachelor’s degree in Ornamental Horticulture and Landscape Design from the University of Tennessee and a Master of Architecture from the University of Washington. After spending 12 years in custom residential design, Billy returned to his construction roots and joined Joe and Wes in 2014. With over 28 years of experience in landscape and residential design and building, Billy brings a thorough approach to the craft focused on executing design intent. He is committed to quality craftsmanship and collaborative working relationships with architects and clients.

Billy is a board member at the Highland Park Improvement Club and prior Co-Chair of the Highland Park Action Committee. When he is not working you can find him on a baseball field in West Seattle with his wife and three sons, or perpetually remodeling their own home.

Wes Yang

Wes has been bringing his attention to detail, business acumen, and exceptional interpersonal skills to the company for over 22 years. He began his construction career while attending the University of Washington where he earned a bachelor’s degree in Construction Management. He spent several years in the field before developing his expertise in estimating, project engineering, and business development. Wes’ authenticity, budgetary experience, and accessible approach allow him to serve as a trusted advisor and partner throughout the entirety of a project.

When not working, Wes enjoys traveling and spending time with his wife and two young children.
