20 Years. One Mission.

It started over 50 years ago along a shared country driveway in what was still orchards, before it became Silicon Valley.

Two kids who became lifelong friends, long before they became business partners.

In the summer of 2006, that friendship became a business built on a simple conviction: that doing right by people was its own reward.

We didn't know then what Sereno would become. We just knew why we were building it. Now we live it.

Twenty years later, with over 650 agents, 20 offices, and over $7 million in charitable giving, we see our agents, clients, and communities that have grown alongside us, and we are humbled.

Thank you for making these 20 years matter.

— Chris Trapani & Ryan Iwanaga, Co-Founders
