Experience Summary

Marc Oberholzer, PE has extensive experience in the design, engineering and permitting of commercial, industrial, oilfield, and natural gas projects. His work involved complete architectural, mechanical, and civil designs, where he has also assisted in developing and maintaining drawing management and Web-based process improvement tools. Marc’s primary areas of focus over his 31 year career have been in civil design, civil engineering, permitting and project management.  Over the past 7 years he’s managed a program of projects for a local, large oil company ranging from $6MM to $15MM of engineering revenue per year.  FEED and Detailed Design Projects varied from small, single-discipline projects (i.e. supporting the installation of a single piece of equipment) to large, multi-discipline projects (i.e. plant expansions requiring multi-discipline engineering).  More recently, he’s managed several projects requiring multi-discipline engineering to convert methane into renewable natural gas here in the San Joaquin Valley.  He directly supervises and coordinates the work of drafters, designers and engineers.
