How she works

Sophia is the person you deal with. Calls and texts come back from her, not from a coordinator, and the same is true at 8pm on a Sunday when an offer deadline moves. That is the concierge standard she carried over from Black Key, and it is the single thing clients mention most often.

For Sellers

A plan before the photographer arrives

Her interior-design background turns preparation into a specific list: what to repair, what to replace, what to leave alone, and what to spend nothing on. Then professional photography, video, 3D Matterport tours, print collateral, and distribution through the Sotheby's International Realty network.

For Buyers

Homes before they are listed

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 ever reached the market.

For Relocations

Town by town, before you tour

Clients moving down from San Francisco get an honest comparison of school districts, commute realities, and neighborhood character first — so the touring starts in the towns that fit your criteria.
