Small by design.

Thorough by habit.

Our story

Started with one house and a better idea.

Keystone began in 2009 when Elena Marsh left a national brokerage with one listing and a conviction: that sellers were paying for marketing reach they did not need and missing the care they did.

Fifteen years on, we still cap the number of homes we take each season. Every one gets a partner, a presentation specialist and a launch plan written for that house alone.

What we hold to

Four promises we put in writing.

01

A partner on every sale

Never handed down to a junior. The person who wins your listing is the person who negotiates it.

02

Honest pricing

We would rather lose a listing than win it with a number we cannot achieve.

03

Presentation included

Styling, photography and film are part of our fee, not upsells.

04

No long contracts

Sixty-day agreements, cancellable at any time. We keep your business by earning it.
