Stream Realty Partners is expanding its SoCal reach, adding a new team and opening a new office in Downtown Los Angeles.

The team, all formerly of Avison Young, will be led by Executive Vice Chairman Jonathan Larsen and Managing Director Chandler Larsen. Jonathan Larsen, a capital markets and leasing specialist, was on AY’s global leadership team and its national executive committee. Chandler Larsen was a principal at AY, specializing in office leasing.

The Downtown LA office team also includes Sally Zesut and Eric B. Moore, both hired as senior vice presidents and both previously at Avison Young. Zesut worked in capital markets for office and industrial, while Moore worked in office leasing and sales.

Stream has existing operations in Orange County and the Inland Empire, but this is its first Downtown LA office.

“This is a deliberate step in how we’re building our platform in California,” Stream Realty President and CEO Chris Jackson said in a statement. “We’re investing in the markets that matter most to our clients and aligning them with teams that can deliver at a high level. That combination is what drives long-term growth for us.”

Also in Downtown, project and construction management specialist Luke Eskigian joins Stream from AY as a vice president, and Sebastian Bernt joins as an associate.

“Los Angeles is a complex and evolving market, and we are excited to build and grow a leading platform here,” Jonathan Larsen said in a statement.
