I graduated from Yale University magna cum laude, served as a Fulbright Scholar in Italy and attended UC Berkeley School of Law. In 2023, I was named a "Legal Visionary" by the Los Angeles Times. I have broad experience in corporate transactions and in serving as outside general counsel to clients. I started my legal career in Silicon Valley and Hong Kong working on large equity and debt financings and matters for private wealth clients. After returning home to Los Angeles, I advised startup companies with formations, acquisitions and day-to-day matters such as sales contracts and licensing. More recently, I have focused on data, IT and SaaS contracts for both providers and customers. My clients include NASDAQ-listed companies, a top ranked children’s hospital and local startups.

I have been a litigator in state and federal jurisdictions throughout the United States for the past 15 years, save for an eight-month stint as General Counsel and Chief Compliance Officer for a credit card processing company. I am an asset to any firm looking for support with any type of motion work or coverage for appearances, if necessary. I like to refer to myself as a self-proclaimed "walking code of civil procedure." I look forward to working with you and helping however I am able. Thank you for your consideration.
