Experience & Representation

Excellence is not optional,
it is my standard, since 2002.

I’ve worked in real estate since 2002, with deep experience in

San Francisco and Washington, DC. Over the course of my

career, I’ve been known for design-forward marketing, strategic

positioning, and a hands-on approach to representing property at

a high level.

Early on, I introduced marketing tools that were uncommon in

residential real estate at the time — including creating San

Francisco’s first property website and developing custom print

and on-site materials that are now widely used across the

industry.

That work shaped how I think about presentation, clarity, and

how buyers engage with property.

I’ve represented nearly $500 million in residential transactions

and have earned multiple“Best of”and industry awards along

the way. In addition to my brokerage network, I maintain a

substantial personal network built over decades, including direct

relationships with more than 2,000 real estate professionals

nationwide and an audience of over 14,000 real estate agents

who follow my work and marketing insights.

My approach blends experience, innovation, and careful

execution. For every propertyI represent, no matter the price

point, my standard remains the same: thoughtful strategy,

disciplined marketing, and attentive representation throughout

the process.
