Since joining SDCC in 1998, Mattix has advanced through a range of roles in event management, sales, and accounting, all contributing to her comprehensive understanding of the organization’s operations. She has served as SDCC’s Chief Financial Officer (CFO) since 2018.
San Diego, Calif. (November 20, 2024)— The San Diego Convention Center (SDCC) announces the promotion of Mardeen Mattix to Deputy Chief Executive Officer & Chief Financial Officer, a newly created position.
In her expanded role, Mattix will provide strategic direction, define and execute business initiatives, manage financial operations, and oversee daily functions to promote efficiency and excellence across SDCC. She assumes this position as SDCC generates record growth and revenue, while preparing for a critical phase of capital improvements.
“Mardeen is a proven leader with a track record of making careful, data-informed decisions to drive success,” said Rip Rippetoe, CVE, SDCC President and CEO. “Beyond her leadership abilities, her dedication to SDCC’s purpose, demonstrated by her 26-year tenure, positions her to help lead SDCC into the future.”
While serving as CFO, Mattix guided SDCC through several pivotal moments, including transforming the building into an emergency shelter during the COVID-19 pandemic. Most recently, Mattix played an integral role in implementing a new sales strategy to attract high-value events that produce significant economic benefits for San Diego. In fiscal year 2025—the center’s 35th year—SDCC events are projected to generate approximately $1.7 billion in regional economic impact, including an estimated $40.2 million in hotel and sales tax revenue for the City of San Diego.
“Driving economic growth and highlighting the vital role of meetings and conventions—not just for SDCC but for the entire region—is an exciting opportunity,” Mattix said.
“I plan to focus on aligning our team toward long-term strategic goals and sustainable growth," she continued. "By fostering a culture of excellence and innovation, and partnering with key stakeholders, we’ll address critical needs to ensure our convention center remains a world-class destination. It's about advancing a thriving economic engine that elevates San Diego and creates opportunities for everyone.”
In 2022, Women in Tourism and Hospitality (W.I.T.H.) recognized Mattix as a W.I.T.H. Honoree for her industry leadership and innovation. The following year, the San Diego Business Journal named Mattix “2023 CFO of the Year” in the nonprofit organization category.
Mattix holds a bachelor’s degree in accounting from Western Washington University. Outside her professional responsibilities, she is an active community member who volunteers on local school committees and mentors students, helping inspire the next generation of San Diegans.
