ABOUT US

OUR HISTORY

Bob Grant Construction has a proud legacy rooted in craftsmanship, integrity, and community commitment. Founded in 1970 by Bob Grant Sr., and later led by his son, Bob Grant Jr., the company earned a strong reputation for delivering high-quality construction and exceptional service throughout the Willamette Valley.

A new chapter began when John Slingluff Sr., who had joined the company as a Senior Estimator and was later promoted to General Manager, purchased the business in 2016 from Bob Grant Jr. With deep respect for the company’s legacy, John brought fresh energy and strategic growth while upholding the core values instilled by the Grant family—Quality and Service. 

Under John’s leadership, Bob Grant Construction has expanded its capabilities and client base, continuing to build lasting relationships and deliver projects that reflect the same dedication to excellence that has defined the company.
