Nine professionals, one shared vision, and a bigger flag planted in Los Angeles. Jonathan Larsen leads a full team into Stream Realty Partners, and it is one of the most energizing growth stories in LA commercial real estate this year.
Stream Realty Partners has expanded its Los Angeles office in the boldest way possible: welcoming a complete nine-person brokerage team, with Jonathan Larsen joining as executive vice chairman, per the company’s announcement this week. The full roster is a celebration of its own. Chandler Larsen joins as managing director, Sally Zesut and Eric Moore as senior vice presidents, Luke Eskigian as vice president, Sebastian Bernt as associate, Austin Cassidy as senior analyst, Arianna Nienow as marketing specialist, and Yolanda Gerardo as senior brokerage coordinator.
Look at that list again, because it honors something the industry too often overlooks: the whole team moved together, from executive vice chairman to senior brokerage coordinator. Production, analysis, marketing, and coordination, one unit, one culture, one decision to build the next chapter side by side. That is loyalty flowing in both directions, and it says everything about how Larsen leads.
Larsen arrives as one of downtown Los Angeles’s most established office brokerage names, with decades of landmark transactions and client relationships built across every cycle the market can throw at a career. For Stream, the fast-growing national firm known for its high-energy culture, the addition delivers instant senior leadership and deep LA roots to anchor its gateway-market ambitions. Growth like this is a vote of confidence in Los Angeles itself: national platforms keep investing in LA because the long-term story, the talent, and the client base are all here, a momentum we track across the SoCal talent market.
There is a beautiful talent lesson in the structure of this move too. Modern teams succeed as ecosystems. The marketing specialist and the coordinator are as essential to the engine as the dealmakers, and the best leaders make sure everyone comes along when opportunity knocks. Companies that understand this, that treat every role as part of the production engine, are the ones winning the hiring trends of 2026.
For Stream’s LA office, the ceiling just rose. For the nine professionals stepping into new business cards this week, a fresh platform and a shared adventure. And for the LA brokerage community, a reminder that this market remains one of the most dynamic places in America to build a commercial real estate career.
Stream’s momentum makes the landing spot even more exciting. The firm has built a reputation as one of the fastest-growing names in commercial real estate by pairing entrepreneurial energy with genuine investment in its people, and its expansion into gateway markets keeps creating room for talent to run. For Los Angeles, that means more competition for excellence, more platforms where great brokers can build, and more proof that the LA market rewards firms bold enough to bet big on it. Everybody wins when the bar rises.
To Jonathan Larsen and the entire team, Chandler, Sally, Eric, Luke, Sebastian, Austin, Arianna, and Yolanda: congratulations. Nine names, one move, zero people left behind. That is how you do it.
