Her Story

Supervisor Dianne Jacob was first elected to the Board of Supervisors in 1992. Now serving a seventh consecutive term, she has held elective office longer than anyone in San Diego County government history.

She represents the more than 620,000 residents of District 2, a roughly 2,000-square-mile region that is the largest of the County’s five supervisorial districts.

It includes the cities of El Cajon, La Mesa, Lemon Grove, Santee and Poway, along with the San Diego communities of Allied Gardens, College Area, Del Cerro, Grantville, Navajo, Rolando and San Carlos. She also represents East County’s unincorporated communities, including Alpine, Julian, Ramona, Spring Valley, Campo and Rancho San Diego.

Dianne is a San Diego State University alumna and a native San Diegan whose roots run three-generations deep. She lives in Jamul.

She has earned a reputation over the decades as a tireless fighter for taxpayers, working to make County government more accountable to the public.

Spurred by a series of catastrophic wildfires in 2003 and 2007, she has led an ambitious effort to overhaul and beef up the region’s fire protection system. She has worked closely with law enforcement to combat human traffickers, sexual predators, scammers and other criminals.

She has spearheaded efforts to help the region’s growing elderly population with initiatives like Choose Well and The Alzheimer’s Project. Dianne helped bring together for the first time the region’s top researchers, health care professionals, universities, elected officials and others to address the devastating impact of Alzheimer’s disease, which has reached epidemic levels in the County.

Expanding youth recreation and improving County libraries are also among her top priorities.

She doesn't back down from a challenge. At a community event, she was once introduced as, "a woman who has the guts to do the right thing, even though it's not the popular thing."

She has been honored with many awards. Among her more recent ones: Local Legislator of the Year, Industrial Environmental Association and the California Manufacturers & Technology Association; Outstanding Commitment to Justice Award, Deputy District Attorney's Association; and the Courage and Hope Award, Alzheimer's Association San Diego.

She has been named “Best Elected Official” at least eight years in a row in the annual East County Californian reader poll. Forum Publications once named her “Most Accessible Politician.”

She has received Legislator of the Year Awards from the California Narcotics Officers Association, Border Solution Task Force, Industrial Environmental Association, San Diego Merchants Association, San Diego Domestic Violence Council, Building Owners and Managers Association and Lean Energy U.S..

She is a recipient of the Women Who Mean Business Award from The San Diego Business Journal and was named Alumna of the Year for San Diego State University, College of Education. She is a San Diego County School Board Hall of Fame inductee, a recipient of the Ninth District P.T.A. Honorary Service Award and a member of the San Diego Alumnae chapter of Gamma Phi Beta. She has also received the Award of Excellence from the Endangered Habitats League.

For her efforts to expose corruption and bring about a leadership overhaul at the San Diego/Imperial Counties chapter of the American Red Cross, she was once interviewed by CBS News correspondent Mike Wallace and appeared on television's "60 Minutes." She was listed among the San Diego Press Club's distinguished "Headliners of the Year" in 2002.

In 2006, she received Governor Arnold Schwarzenegger’s California Recreational Trails Committee Award. The honor recognizes individuals who have made significant contributions in support of trails in California.

Prior to her election to the Board of Supervisors, Dianne worked as a public school teacher in Spring Valley and served as  a member of the Jamul-Dulzura Union School District Board for 17 years. She was active in the California School Boards Association and served as its President in 1987.

She enjoys horses and country-western music. She and her family own a ranch in the backcountry.
