Our Advantage
Every agent on the Peninsula has access to the same MLS. The difference is who answers the phone, who knows what's trading privately, and who can tell you honestly what your home needs before it's photographed.
Sophia is the person you deal with. Calls and texts come back from her, not from a coordinator — including at 8pm on a Sunday when an offer deadline moves. That standard came out of Black Key Luxury Lifestyle Concierge, the company she founded before real estate, serving clients for whom "I'll have someone get back to you" was never an acceptable answer.
It is also why her business splits close to evenly between listing and buyer representation each year rather than specialising in one. Working both sides keeps her current on how Peninsula transactions are actually being negotiated, not on how they were negotiated eighteen months ago.
Sophia's earlier career was in interior design, which turns "get it ready" into a specific list: what to repair, what to replace, what to leave alone, and what to spend nothing on. Sellers get a plan before the photographer is booked; buyers get an honest read on what a property could become.
A meaningful share of high-end Peninsula inventory trades privately, and access comes from agent relationships rather than portals. One of Sophia's Hillsborough sales closed at $11,500,000 before it reached the market. At this price point, being inside that network is the whole game.
Professional photography, video, 3D Matterport tours and virtual walk-throughs, print collateral, and distribution through the Sotheby's International Realty network — a brand with reach into exactly the international buyer pool that shops Hillsborough and Atherton.
Sophia grew up here and knows these towns block by block. For the many clients relocating down from San Francisco, that means an honest comparison of school districts, commute realities, and neighborhood character before anyone tours a house.
Sophia is a member of the California Collective, a group of top-producing California Sotheby's International Realty® agents. If your move takes you to Tahoe, Santa Barbara or San Diego, the referral is to someone she knows, not a name off a list.
