Top-producing California agent joins eXp Realty

Costanza Genoese Zerbi — a nationally recognized real estate agent and founder of Long Beach, California-based Costanza Genoese Zerbi & Associates — has joined eXp Realty, the company announced Tuesday.

Zerbi, a veteran agent with nearly a decade of experience, brings a strong sales record to the brokerage. She closed $91 million in volume during a peak year and finished 2024 with $65 million across 65 transactions.

Her goal, she said, is to surpass her previous benchmark.

“I joined eXp to get back to my $91M year — and beyond,” Zerbi said in a statement. “This is a high-level, high-output environment that rewards drive, collaboration, and results. I’ve found the platform, the people, and the freedom that will help me scale again.”

Before joining eXp, Zerbi worked with Coldwell Banker and Redfin. She cited the independence and support that eXp offers as key reasons for her move.

“I was looking for that rare mix of strong infrastructure and zero bureaucracy,” she said. “eXp gives me the tools and autonomy to operate at my best.”

Born in Italy and fluent in multiple languages, Zerbi credits her international background for helping her build connections with a diverse clientele. She holds degrees from the University of California at Berkeley and UCLA, and she previously worked in corporate marketing before entering real estate.

Her performance has earned national recognition. Zerbi has been ranked in the RealTrends Verified Top 500 for both volume and sides, and her work has been featured in numerous national outlets.

Her husband, Neil, will be joining her in the business as the pair expand their real estate team. “We’re building something together that’s grounded in excellence and powered by eXp,” she said.

“Costanza represents the kind of visionary leadership and production-level excellence that thrives at eXp,” Leo Pareja, CEO of eXp Realty, said in a statement. “She’s not only a top producer, but also a collaborative force in the industry. We’re thrilled to welcome her to eXp and can’t wait to see what she accomplishes next.”
