    Entity formation. Mergers and acquisitions. Commercial contracts. Corporate finance.

I have had a sophisticated business law practice for over 20 years. I primarily represent companies and high net worth individuals in complex lawsuits and securities transactions. My work also involves entity formation, corporate governance and commercial contracts.

In my litigation practice, I represent plaintiffs and defendants in a broad array of commercial disputes. These range from conventional breach-of-contract and business tort actions to more complicated disputes arising from real estate investment vehicles, financial elder abuse and disagreements among business partners. I have prevailed numerous times before the Ninth Circuit Court of Appeals.

Before joining Capobianco Law Offices, I practiced in Los Angeles for 10 years and also in Chicago and Silicon Valley. Eight years of my career were spent at O’Melveny & Myers, a leading global law firm. At O’Melveny, I closed over $15 billion dollars’ worth of securities and M&A deals.

In 1997 and 1998, I served as clerk to Chief Justice E. Norman Veasey of the Delaware Supreme Court.

In 2018, I received the Hon. Benjamin Aranda III Outstanding Public Service Award from the L.A. County Bar Association for my pro bono work on behalf of domestic violence victims.

I received my Bachelor of Arts degree from UCLA and my law degree from Stanford Law School, where I was selected to join the Order of the Coif.
