The Modesto Chapter covers six counties: Calaveras, Madera, Mariposa, Merced, Stanislaus, and Tuolumne, representing approximately 4,000 Cal Poly alumni.
Alumni in this area work in the wine and agriculture industries as engineers, operations manager, sales and education. Large employers include E. & J. Gallo Winery, Foster Farms and G3 Enterprises, a printing company.
The Modesto Chapter hosts the Modesto Fork ‘N Bottle and a fundraising golf tournament each year to raise scholarships for local Cal Poly students. Another annual event, the Fall Social at the Durrer Barn, brings together local alumni for a kid-friendly barbeque.
