Atherton is the kind of place that does not reveal itself until you are already inside it. There are no storefronts, no sidewalks, and no open houses on Sunday afternoons. What there is: one-to-three-acre estates behind gates and oak canopies, a ten-minute drive to the world’s densest concentration of venture capital, and some of the most sought-after school addresses on the Peninsula. Twenty years of working in this market has taught me that the buyers who succeed here are the ones who start the conversation before the listing appears, not after.
