Our History: A Legacy of Service to Cities

Since 1981, RKA Consulting Group has been a trusted partner for cities across the Greater Los Angeles area—delivering high-quality, cost-effective civil engineering solutions. Drawing on his extensive experience with the Los Angeles County Road Department and multiple Public Works Departments, Ron Kranzer founded RKA with insights gained from working within city operations. This background gave RKA a unique understanding of municipal needs, processes, and priorities during our early years—knowledge that has remained essential to our growth and success over time.

Today, RKA is a well-respected civil engineering firm recognized for our dedication to reliability, efficiency, and excellence. Public agencies turn to RKA for infrastructure improvements, plan check services, public works support, and more. Our focus on delivering reliable service and fostering collaboration helps us continue to build lasting relationships—not just as consultants, but as trusted extensions of city staff.
