As a fifth generation Cambrian, Bob grew up in Cambria on his family cattle ranch. After attending Coast Union High School he graduated from Cuesta College and Cal Poly in San Luis Obispo. The love of history has always been important to Bob and this appreciation culminated with the writing of the Soto family history dating back to 1776 in California.
Bob believed it was critical to document family stories which include ten generations of Californians so they would be preserved for the future. Bob also continues to write occasional articles in the local newspaper which subjects often combine agriculture and history—two important aspects in his life.
