OCTA Board Selects Tam T. Nguyen of
Fountain Valley to Serve as New Chair

The Board of Directors of the Orange County Transportation Authority unanimously selected Tam T. Nguyen as its new chair for 2024.

The Board also appointed Doug Chaffee to serve as Vice Chair and four members were sworn into new terms on the Orange County transportation board.

With an annual budget of $1.7 billion, OCTA is responsible for planning, funding and delivering public transportation improvements for Orange County.

Last year, Chair Nguyen served as vice chair on the OCTA Board of Directors. He replaces outgoing Chairman Gene Hernandez.

Nguyen, a Fountain Valley resident, is a community and education leader.

“Since being appointed to serve as a public member on the OCTA Board in 2021, I have witnessed firsthand how much this agency is making a difference in helping to enhance travel options for residents, businesses and visitors,” Nguyen said. “I am grateful for the tremendous amount of trust of my fellow board members in selecting me as their chair, and I look forward to working with them as stewards of the public’s funds to continue innovating and delivering a balanced, equitable and sustainable transportation system for Orange County’s diverse communities.”

Chair Nguyen serves as one of two public members on the OCTA Board, and he has served in that capacity since April 2021. Nguyen has been a member of OCTA’s Diverse Community Leaders Group since its creation more than a decade ago.

Nguyen is also respected throughout the county as a leader in business and philanthropy. He is co-owner of Advance Beauty College, a second generation, family-owned business that was founded in 1987. Over 50,000 students have graduated from its innovative training with many becoming successful entrepreneurs, beauty manufacturers and salon owners in the beauty-care industry throughout North America.

Under his leadership as president from 1999 to 2022, Advance Beauty College has become nationally recognized for its manicuring program. It has been honored as a Civic 50 OC, Excellence in Education, Center for Family Business Hall of Fame Commitment to Education Award and Inaugural Golden School Award from the American Association of Cosmetology Schools.

Nguyen teaches business management at California State University, Fullerton, and is past president of the university’s alumni association. In 2015, he received the Cal State Fullerton Vision & Visionaries Award. He is currently the chair of the Cal State Fullerton’s Philanthropic Foundation Board of Governors.

In addition to his leadership with Advance Beauty College and Cal State Fullerton, Nguyen serves on the board of directors for Genesis Bank, MemorialCare Orange Coast Medical Center & Saddleback Medical Center, Small Business Diversity Network, Orange County United Way, Pro Nails Association, Center for Family Business, Garden Grove Police Chief’s Advisory Council and recently the board of the Garden Grove Community Foundation, Vietnamese American Chamber of Commerce and Project Vietnam Foundation.

During the COVID-19 pandemic, Nguyen co-founded Nailing It for America, a volunteer group that helped collect and deliver nearly $30 million worth of personal protective equipment for healthcare professionals, frontline workers and vulnerable community members.

Chair Nguyen was 1 year old when he and his family arrived in California in 1975 at the end of the Vietnam War. He and his wife are proud to be raising their three children in Fountain Valley and to be part of Orange County’s vibrant Vietnamese American community. He is a local college graduate who studied at both UC Irvine and Cal State Fullerton.

Newly appointed members of the OCTA Board include: Anaheim Mayor Ashleigh Aitken, Santa Ana Mayor Valerie Amezcua, Garden Grove Councilmember Stephanie Klopfenstein and Costa Mesa Mayor John Stephens.

The OCTA Board is comprised of 18 members, including the five county supervisors, two members from city councils in each of the five supervisorial districts, two public members and the Caltrans District Director serves in a non-voting ex-officio capacity.

I-15 Express Lanes Extension to Lake Elsinore Moves Along

Extending the I-15 Express Lanes south beyond Cajalco Road in Corona is part of RCTC’s 10-Year Western Riverside County Delivery Plan to deliver traffic relief to the growing communities along the I-15 corridor. With the approval of the Project and Construction Management (PCM) contract to Parsons, the Commission is getting ready to line up contractors and agency agreements to begin construction on the 15 Express Lanes Project Southern Extension (ELPSE) by 2026.

The 15 ELPSE will construct two express lanes in each direction from Cajalco Road to State Route 74 (Central Ave.) in Lake Elsinore. This 14.5-mile extension of the Riverside County express lanes system is designed to bring much-needed mobility options to the area. Over the past 20 years, the community of Temescal Valley and the cities of Lake Elsinore and Corona have grown tremendously, bringing with it new housing, residents, and increased travel throughout the region.

Once complete, the new express lanes will give motorists an option for a reliable commute between Lake Elsinore, the 60, and Orange County. With additional lanes, congestion relief of the general-purpose lanes is possible, improving traffic operations. The 15 ELPSE will also help improve transit and rideshare options by providing free-flowing lanes to buses and commuters that carpool or vanpool. This cost-effective commute opens possibilities for new routes and employers to incentivize employees to avoid solo car trips.

The Commission will use an innovative progressive design-build project delivery method to speed up construction. Unlike traditional construction-bid delivery methods, the progressive design-build method will allow RCTC to engage with the design-build contractor earlier, enabling solutions that save funding and help maintain the construction schedule. This progressive design-build approach is vital as the Commission continues to assemble funding for this project. With this process, RCTC will have the option to build and deliver the project in phases. This innovative project method is made possible by the passage of recently approved Senate Bill 617.

The project is a partnership between RCTC and Caltrans and will be funded with a combination of federal and local sources. Sign up to receive project updates at

Elected by the OCTA Board to serve as Vice Chair for 2024 was Director Doug Chaffee.
