Rooted in Denver

Empowering Communities Through Engineering Excellence

In 2009, Stan Kobayashi, decided it was time to “build another bridge” after 33 years in bridge, structural, and civil engineering. Instead of working for others, he decided it was time to start his own company. With the idea of keeping the firm small, responsive, and focused on bridges and structures, he started the Kobayashi Design Group, LLC (dba KDG Engineering LLC). He wanted the firm to be based on a few guiding principles. We seek to develop our personnel and focus on good work and communication. We are dedicated to our clients, employees, and our community. We see to prosper others before we can prosper. Every year, KDG works to empower the youth of Denver through different programs and time donations. We contribute to the Asian and Pacific Islander youth awards and are proud members of the NAAAP (National Association of Asian American Professionals). Additionally, KDG takes on an internship from John F. Kennedy High School, which is interested in STEM, every year through the Career Launch program.
