Kristen Sullivan has spent more than two decades earning the trust of a client base most brokers never quite crack: financial institutions navigating real estate decisions with real regulatory weight behind them. She has now joined Stream Realty Partners as Vice President in the firm’s Los Angeles office, part of the same wave of talent giving Stream’s newest platform real staying power.
Sullivan joins Stream’s Office Tenant Representation practice, coming over from Avison Young where she served as Vice President. She arrives alongside Hayden Eaves, joining as Executive Vice President, and Jill Bartolome, joining as Senior Brokerage Coordinator. All three are stepping into Stream’s recently launched Los Angeles office, led by Jonathan Larsen as Executive Vice Chairman & Partner, Greater Los Angeles Area Market Leader, alongside Chandler Larsen as Managing Director, as the two build out Stream’s presence across Los Angeles and Ventura County.
Sullivan’s approach has always been relationship-first. Before focusing on commercial real estate, she spent years building a career in sales and client service across other industries, and she has carried that same instinct directly into her brokerage practice. Her expertise spans tenant representation, landlord representation, lease negotiations, acquisitions, and long-range real estate planning, and her client list reflects just how deep her focus on financial institutions runs: Bank of Hope, Hanmi Bank, Tri Counties Bank, USC Credit Union, and roughly two dozen financial institutions in total have trusted her to negotiate leases and acquisitions that support their growth and long-term stability. She holds a Bachelor of Science in Organizational Management from the University of La Verne. That breadth of relationships did not happen by accident. Financial institutions do not switch brokers casually, and building a client list this concentrated in one sector takes years of proving an advisor understands both the real estate and the regulatory pressure sitting on top of it.
Representing both landlords and tenants across her career has given Sullivan something a lot of brokers never fully develop: a genuinely two-sided view of the negotiating table. She knows what a landlord needs to see in a deal to say yes quickly, and she knows what a financial institution needs in a lease to satisfy examiners, boards, and long-term operating plans that stretch a decade or more into the future. That is a different skill set than closing a single transaction well. It is the skill set required to keep a client’s real estate strategy sound across dozens of decisions over many years, which is exactly the kind of long-horizon trust financial institutions look for in an advisor.
Sullivan’s commitment to the credit union community goes well beyond client work. She serves as a Council Member with Emerging Credit Union Leaders and as Vice-Chair Board Member of Pasadena Federal Credit Union, seats that put her inside the same institutions she advises, thinking about their long-term health from the inside rather than just the outside. That kind of dual perspective, sitting on a credit union board while also representing credit unions in real estate negotiations, is not common, and it gives her clients a level of trust that is difficult to manufacture any other way.
This move is also a reunion story on more than one level. Sullivan, Eaves, and Bartolome all came from Avison Young, following a path that Jonathan Larsen and Chandler Larsen cut first when they launched Stream’s Los Angeles office earlier this year, also arriving from Avison Young’s leadership ranks. A team that already knows how to work together does not have to spend its first year figuring out each other’s strengths. It can spend that time serving clients. For an office built specifically to become a best-in-class office tenant representation platform, that head start matters. It also gives Stream a foothold beyond the city itself: the mandate handed to Larsen and Chandler Larsen extends the platform’s reach into Ventura County as well, a market where financial-institution relationships built over decades carry particular weight.
Stream Realty Partners President and CEO Chris Jackson framed the broader strategy behind moves like this one plainly when the Los Angeles office first launched: the firm is investing in the markets that matter most to its clients and aligning them with teams built to deliver at a high level. Sullivan’s addition is a direct continuation of that plan. Los Angeles is one of the most competitive commercial real estate markets in the country, and a platform’s credibility with financial institution clients in particular depends on advisors who already have those relationships built, not advisors starting from zero.
It is the same pattern we track across the SoCal talent market again and again: the strongest moves rarely involve a single person chasing a bigger title alone. They are trusted relationships reassembling themselves at a new address, the way Hayden Eaves followed the colleague he came up with, and the way Sullivan is now doing the same, bringing two decades of financial-institution focus that made her exactly the kind of proven relationship Stream’s Los Angeles platform needed on day one.
To Kristen Sullivan: congratulations on the new chapter. Two decades of earning trust one financial institution at a time is exactly the kind of track record that makes a launch team worth betting on.
