In 1992 the voters elected Dianne to the position of San Diego County District 2 Supervisor where she served for 28 years before being termed out in 2021. As the longest serving San Diego County Supervisor, Dianne led the development of the San Diego County Fire Protection District; co-authored the county’s Multiple Species Conservation Plan, preserving over 100 acres of open space; led the effort to open the Santa Ysabel Nature Center; worked to improve over 400 miles of trails including public access along the San Diego and San Dieguito Rivers; launched the Alzheimer’s project; and championed the development of hundreds of youth recreational facilities. For that work as well as other accomplishments, Dianne has received dozens of awards.
