About me

I know these roads like the back of my hand

I grew up watching the fog roll over the Sonoma hills every morning. This county isn't just where I work — it's where I live, where I raise my family, and where I've built every relationship that matters to me.

When you work with me, you're not getting a transaction. You're getting a neighbor who will walk every property with you, answer every call, and make sure you feel at home long before you sign anything.

Why work with me

Real estate the way it should feel

Rooted in Sonoma

I was born and raised in Sonoma County. I am happily raising my children in Petaluma where I grew upI know which neighborhoods flood in winter, which streets catch the best afternoon light, and which blocks are about to become the next hidden gem.

Honest, always

I'll tell you when a house isn't right for you — even if it means losing the sale. My reputation is built on clients who trust me, not on closing numbers.

With you every step

From the first showing to the day you get your keys, I'm available. No handoffs to assistants, no unanswered texts. Just me, fully present for one of the biggest decisions of your life.

What clients say

She didn't just find us a house — she found us a life. We told her what we dreamed of and she listened. Three months later we were watching the sunset from our own vineyard porch.

The Callahan Family

Healdsburg

I've bought and sold four homes in my life. This was the first time I felt like the agent was genuinely on my side. She negotiated hard for us and never once made us feel rushed.
