A Growing Local Firm

LDC has seen tremendous growth over the past 20 years, yet we remain committed to our local roots and actively support community organizations and charities in each of the cities we call home. Our headquarters is in Woodinville just 30 minutes northeast of Seattle. We also have offices in Kent and Olympia. With three locations to choose from, you can work close to home and truly have a work/life balance. Whether you’re looking for great restaurants, wineries and breweries, a family-focused neighborhood close to work, access to the great outdoors, or proximity to a big city life, our offices are at the heart of it all. Join our team and become part of a dynamic and supportive work environment.
