Many of the clients that we began with in 1959 are still with us today.

Over the years, customers throughout the Southwest US have come to rely on Herman Weissker for their utility construction services. When Herman Weissker started this company, he had a simple philosophy – do it right the first time, every time. Today, Herman Weissker, Inc. still follows still follows this philosophy.


Herman Weissker, Inc. was founded in 1959.

We originally focused on building conduit infrastructure when Southern California Edison Company and General Telephoned Company became the core focus or our business. In the following years, Weissker became an industry leader in electrical and gas underground system installation. In 1988, Herman Weissker started the Engineering and Construction Management division. As part of our “design-build” approach, we plan the work and oversee construction management. The Engineering and Planning groups now perform administrative services for public utilities that include: procurement, scheduling, and material management.
