Our team

Bob’s decision to take geology as an elective science course at Pasadena City College (PCC) was influenced by a neighbor who taught there and returned from weekend field trips to the desert with great stories and photographs. Geology classes at PCC taught by two of the best professors Bob had in college sealed the deal. Bob transferred to UCLA where he completed a BS in Geology in 1979 and MS in Engineering in 1982. Bob worked as a geologist and engineer at Kovacs-Byer until leaving in 1988 to join Dave Grover as the Principal Engineer at Grover-Hollingsworth and Associates.

Bob’s expertise in geotechnical engineering has been applied to complicated hillside projects, landslide restoration and evaluation of damaged properties. Bob reviews geotechnical reports prepared by the staff. Bob also provides expert services for attorneys and insurance companies. When not working, Bob enjoys skiing, fishing, gardening and attending basketball and football games.
