Print As 2020 winds down, so does the political career of Supervisor Dianne Jacob, who retires from the San Diego County Board of Supervisors next month after seven consecutive terms — 28 years — representing District 2. In addition to many other efforts over the years, Jacob leaves her mark on the county’s community living with Alzheimer’s disease and related dementias, as well as the family caregivers who tend to their needs. Jacob, who was born and raised in San Diego, attended Grant Elementary School in Mission Hills before moving to La Mesa, where she went to Rolando Elementary School, La Mesa Junior High and Helix High School. She went on to earn her degree in elementary education and a teaching credential at San Diego State University.
