A Brief History

Michael F. Ronca & Sons, Inc. – Family Owned and Operated for Three Generations
Our roots date back to 1940, when our founder, Fred Ronca, established a successful residential and light commercial plumbing company, Fred Ronca & Sons Plumbing, Inc. Through the years this multi-generational family-owned company provided much needed services to a growing Lehigh Valley population. In 1979, son Michael F. Ronca began an underground utilities construction firm Michael F. Ronca & Sons, Inc. With the untimely passing of Michael F. Ronca in 1985 his five sons immediately assumed leadership roles in the company and continued his legacy expanding into the water & wastewater industry.
