Legal counsel for teams whose problems now touch product, data, AI, and operations
I am a corporate lawyer and builder. I help companies, legal teams, and firms handle the work that falls between legal advice and execution: contracts, governance, privacy, compliance, AI adoption, internal workflows, and the software layer that makes the work repeatable.

/ ABOUT
I am Teachable's sole counsel and I help teams fix the handoff: where counsel gives advice, operators need a process, engineers need specifications, and nobody owns the system. My practice is built for that seam.
