Our History

Weber, Ghio & Associates - Roark Weber Civil Engineer

After resigning in 1979 as Calaveras County’s Public Works Director and County Surveyor, Roark Weber opened a one-room civil engineering office on East St. Charles Street (formerly Pat Casey’s Land Surveyor’s office) in San Andreas. Initial clients were private but soon the City of Angels Camp, Union Public Utility District (UPUD), and the City of Sutter Creek became clients. One of the first projects was for UPUD who had received grant funding to upgrade their water treatment and distribution system which included the construction of the Cademartori Reservoir and a new water treatment plant.

Weber, Ghio & Associates - Weber Hall Consulting Group

This new work required grant and management skills that brought Ed Hall and Larry Thompson into the company, then renamed, Weber Hall. These and other new clients: Amador City, City of Ione, and Valley Springs Water and Sewer District generated need for additional support staff and brought Nancy McCartney, in 1986, who is still with the firm.

Weber, Ghio & Associates - Weber Ghio Associates Professional Engineers

The firm’s government client group continued to expand to include the City of Jackson and Amador County’s Department of Public Works. Ed Hall left the firm in 1989 and led to the hiring and ultimate partnership with Gary Ghio. Gary incorporated the firm in 1993 when it was renamed Weber, Ghio, and Associates. The partners purchased the old Huberty House and property at 394 East St. Charles in San Andreas and made it the new office. They also purchased and opened an additional office in Sutter Creek at 201 Hanford Street. Roark retired in December 2013, selling his interest in the business and the two properties to his partner, Gary Ghio.

In February 2018, Gary sold his interest in the business and the two properties to Matt Ospital who started with the firm in 2008.  The change in ownership led to the rebranding of WGA and a new logo.
