What's behind every Kathi Constanzo, CCIM, SIOR engagement — the team she's part of, the mentor she came up under, and the global network supporting both. Three institutions, one stack, all in service of her clients.
In 2023, Coldwell Banker Commercial honored Bill Ukropina and Kathi Constanzo, CCIM, SIOR together with the national Mentor / Protégé of the Year award — recognizing one CBC team whose dedicated mentor has demonstrated leadership by formally guiding a colleague to a successful practice in commercial real estate, and whose protégé has demonstrated commitment and promise to the CBC franchise system.
Bill Ukropina has been one of Pasadena's leading commercial real estate brokers for four decades. He is the founder and managing leader of Team Ukropina, and the mentor under whom Kathi built her commercial real estate practice from her first year forward.
Bill's career spans more than five hundred commercial lease transactions and a roster of landmark deals that have shaped the Pasadena and San Gabriel Valley commercial fabric. He co-founded the North County office of Coldwell Banker Commercial in 2006 and served as President of CBC's Office Properties Division through 2018. The 2023 Mentor / Protégé of the Year award — recognizing his work formally guiding Kathi into commercial real estate — is one of many CBC recognitions Bill has earned across his career.
For Kathi, his mentorship is the institutional backbone of her practice. Every engagement she takes on draws on Bill's four decades of Pasadena relationships, deal history, and market memory — the kind of context that can't be bought and can't be shortcut.
Team Ukropina is one of the most decorated commercial real estate teams in the Coldwell Banker Commercial network — ranked #1 CBC team in California and consistently among the top CBC teams in the country. The team's focus is the 210 corridor through the central San Gabriel Valley: Pasadena, Arcadia, and Monrovia. Within that corridor, no team has more institutional knowledge, deeper owner relationships, or a longer track record.
That depth shows up in the team's award history. CBC Circle of Distinction · Platinum recognition every year from 2020 forward. The 2023 Mentor / Protégé of the Year. A consistent presence on CBC's national leaderboards. The team's specialization — local depth backed by global resources — is exactly what high-stakes commercial real estate clients need.
For Kathi, being a Executive Vice President of Team Ukropina means clients get her direct attention plus the collective experience of a team that has worked this market with depth and continuity since long before she entered the business.
Coldwell Banker Commercial is one of the largest and most established commercial real estate organizations in the world. For Kathi, CBC means three concrete things: institutional reach when a deal extends beyond the SGV, cross-market specialists when a property type requires deep expertise she doesn't have herself, and institutional marketing infrastructure that boutique brokers can't match.
The numbers — direct from CBC's 2025 Brand Claims — make the scale visible.

CBC's global footprint means Kathi can move a deal forward whether the next step is in Pasadena, Orange County, or another state. The network's marketing infrastructure surfaces qualified prospects far beyond what a boutique broker can reach. And the institutional ethics ranking matters: when 96% of CRE decision-makers rate CBC's service excellent, that's the bar Kathi works under every day.
"Every client I work with gets me personally — I answer my phone, I draft the offers, I stay on every deal. But what stands behind me is the part most clients don't see at first: Bill's four decades of Pasadena relationships, Team Ukropina's depth across the 210 corridor, and the global reach of Coldwell Banker Commercial. That's the institutional backing on every transaction." — Kathi
Bill Ukropina built Team Ukropina over four decades. Kathi joined in 2019 and was named his Protégé of the Year by 2023. The institutional weight behind her practice is the work of generations. Fifteen minutes with Kathi and you'll feel it.
