For more than 40 years, CNC Engineering has built a legacy of engineering excellence, trusted partnerships, and dedicated service throughout Southern California. Founded by Clem Calvillo, CNC’s roots are deeply connected to the San Gabriel Valley and the City of Industry, where Clem began his engineering career after graduating from Cal Poly Pomona and serving two years in the U.S. Army. The mentors and community leaders who shaped those early years helped establish the values that continue to guide CNC today.
From those early roots in the City of Industry, CNC’s reach and expertise expanded throughout Southern California. Over the decades, the firm has partnered with cities, public agencies, and other organizations to plan, design, and deliver critical public works and infrastructure projects that support the communities they serve. What began with strong local relationships grew into a broad portfolio of experience built on technical expertise, responsiveness, and a commitment to delivering lasting value for our clients.
At the heart of CNC’s success is its people. Through periods of growth, change, and challenge, Clem’s steadfast leadership and faith have helped guide the company forward while creating a culture that values integrity, teamwork, accountability, and the contribution of every employee. Today, those principles continue through CNC’s talented team of engineers and professionals and the next generation of company leadership.
Celebrating more than 40 years is both an opportunity to honor where CNC began and a reflection of how far the company has come. With four decades of experience behind us and a continued focus on the future, CNC remains committed to serving our clients, investing in our people, strengthening Southern California’s infrastructure, and Engineering the Future with Excellence.
