WHAT CLIENTS SAY

"Yvette has been a particularly effective litigator for us recently."
"She is exceptionally smart."


MY CLIENT PHILOSOPHY

"I work very hard to understand the business and legal context of my clients’ issues, and I treat them as my own. Early in a matter, I define with input from clients what a “win” looks like and check back throughout the matter to make sure their goals have not changed. This approach allows me to deliver the best guidance to clients—leading to the result they want in the most efficient manner. I develop a strategy based on each client’s specific goals and also plan for any ripple effects to the business, so I not only deliver the win but also proactively put the client in the strongest possible position for the future."
