I'm a California-licensed attorney with 18+ years of experience helping everyone from Fortune 500 companies and venture-backed startups to individuals navigating real-life legal situations. My career started at Fenwick & West, one of Silicon Valley's top law firms, where I worked alongside names like Google, Airbnb, Kleiner Perkins, and Sequoia Capital. From there I moved in - house at companies like Cloudflare, Autodesk, and Enphase - which gave me a practical, business-minded perspective that I bring to every client, no matter the size of the matter.

I'm direct, responsive, and I speak plain English — not legalese. Whether you're a founder closing your first deal or an individual facing a situation you've never navigated before, I'll give you the same level of attention and care.
