San Gabriel Valley depth. Greater Los Angeles reach.

Kathi's office is at 388 South Lake Avenue in Pasadena, and her four primary markets — Pasadena, South Pasadena, San Marino, and Arcadia — sit in the heart of the San Gabriel Valley. But her practice extends throughout Los Angeles County for the right engagement: marquee transactions, longtime client relationships that have moved outside the SGV core, and cross-jurisdictional deals that benefit from her professional discipline and attention to detail.

In LA County terms, that means active transactions across the entire region. From West LA to the East San Gabriel Valley, from the Foothills down to the Westside, Kathi has worked deals at scale. The backbone of her practice is the relationship-driven SGV market she knows better than anyone — but she's brought clients across LA county lines, and into Orange County and beyond, when the work called for it.

Behind every engagement: the institutional resources of Coldwell Banker Commercial (2,800+ professionals across the global network), the depth of Team Ukropina, and Kathi's own twenty-plus years building relationships across the LA business community.

Beyond LA County

When clients have asked Kathi to work outside LA County, the CBC network supports it. Past and ongoing engagements have reached Orange County (Newport, Irvine, Anaheim), the Inland Empire, and select Bay Area properties — all anchored by long-standing client relationships rather than market expansion for its own sake.

What Kathi Doesn't Chase

Kathi doesn't market herself as a generalist LA broker. The Pasadena and SGV core is where she builds and renews relationships; everywhere else is by client referral or because a specific deal calls for it. That focus is intentional — it's what makes the depth in her primary markets possible.

The CBC Network Multiplier

For any transaction outside Kathi's direct expertise, she draws on Coldwell Banker Commercial's 3,334 professionals across 158 offices in 45 countries. Co-broker arrangements, cross-market introductions, and institutional reach are built into how she works.

FAQ

Greater Los Angeles commercial real estate, answered.

Common questions about Kathi's reach across LA County and the kinds of engagements she takes on.

What areas of Greater Los Angeles does Kathi serve?

Kathi's four primary markets are Pasadena, South Pasadena, San Marino, and Arcadia — the San Gabriel Valley core, all served from her office at 388 South Lake Avenue in Pasadena. Beyond those four, she takes on engagements across the broader SGV (Altadena, Sierra Madre, La Cañada Flintridge, Monrovia, Duarte, San Gabriel, Alhambra), Downtown LA, Glendale and Burbank, the San Fernando Valley, and the Westside — typically through long-standing client relationships rather than market expansion.

Does Kathi take on transactions outside the San Gabriel Valley?

Yes — when the relationship or property calls for it. Past engagements have reached Downtown LA, the Westside, the San Fernando Valley, Orange County, the Inland Empire, and select Bay Area properties. Kathi doesn't market herself as a generalist LA broker, but for marquee transactions or longtime clients moving outside the SGV core, she has the experience and the CBC network to deliver.

Why is Kathi's practice concentrated in the SGV?

Focus produces depth. Kathi's four primary markets — Pasadena, South Pasadena, San Marino, and Arcadia — share architectural character, regulatory dynamics, and a tight broker-and-owner network that rewards relationships built over decades. Working those four markets with full depth makes her substantially more effective than a generalist who's spread thinner across all of LA County. When clients ask for work outside the SGV, she takes it on — but the core is intentional.

How does Coldwell Banker Commercial extend Kathi's reach?

CBC operates one of the largest global commercial real estate networks — 3,334 professionals across 158 offices in 45 countries. When a client needs work outside Kathi's direct expertise (a different city, a specialized property type, an out-of-state acquisition), she has access to co-brokers and specialists across that network. The result: Kathi leading the deal personally, with Team Ukropina's depth and CBC's institutional resources behind her.

What types of commercial transactions does Kathi handle across Greater LA?

The full range. Tenant representation (office, retail, medical, industrial), landlord and owner representation (marketing, leasing, disposition), investment sales (acquisition and disposition of income-producing property, NNN, 1031 exchange strategy), and strategic advisory for owners and family operators making once-in-a-decade real estate decisions. Each service has its own page with more detail.

How do I figure out if Kathi is the right broker for my situation?

The fastest path is a fifteen-minute conversation. Kathi answers her own phone and returns her own emails. If your transaction is in or near her primary SGV markets, she'll likely have direct context for it. If it's elsewhere in LA County or beyond, she'll tell you honestly whether her network is the right fit — and if it's not, she may refer you to someone better positioned. Email Kathi or call 626.898.2308 to start.
