On January 4, 2021, Diane Nguyen started the position as the Executive Director of the San Joaquin Council of Governments (SJCOG). The SJCOG Board of Directors unanimously appointed her at its October 22, 2020 meeting after a nationwide executive recruitment.

“No project is too big, nor is any project too small, for Diane,” Assemblymember Jim Cooper said. “She has turned around situations by engaging directly with stakeholders.   This kind of responsiveness to community needs is what has defined Diane’s career.”

SJCOG Chair and City of Stockton Councilmember Sol Jobrack said, “We welcome Diane Nguyen as the Executive Director.  With 25 years of direct experience working in regional and city governments throughout California, she brings deep strategic and operational expertise that are extremely valuable to the region.”

During her 8-year tenure as SJCOG’s Deputy Director of Planning, Programming, and Project Delivery, Diane was a pioneer for many innovative projects in the San Joaquin region.  She developed San Joaquin’s first Regional Transportation Plan/Sustainable Communities Strategy and first 7-public transit agency mobile ticketing application (known as EZHub).  She oversaw the Measure K Capital Improvement Program which helped fund the first I-5 HOV lanes in the Central Valley and the first Diverging Diamond Interchange in California at State Route 120/Union Road.

“SJCOG looks forward to Diane’s guidance to the Board of Directors and continuation of efforts she led this past year,” Jobrack said. “This includes the Regional Early Action Planning Program for housing and the launch of a concept she created to bring electric bikes, electric cars, and work force development into Stockton’s disadvantaged communities.”

“As Executive Director, I will foster SJCOG’s purpose driven culture--one focused on the delivery of exceptional service to SJCOG’s member agencies, partners, and San Joaquin residents,” Nguyen said.  “In 2021, I am thrilled to be able to grow creative concepts for more sustainable and cost-effective mobility options.  I will also explore all opportunities to leverage transportation dollars for the region.”
