Personal Note

As an attorney, I've been privy to stories and dramas both epic and tumultuous, and have had the honor of working with a wide variety of clients. Every case and every client presents new and interesting challenges. Each deposition is a window into a different life and each claim presents new questions and opportunities for the client and me alike. As Samuel Johnson once said, when a person "tires of London, he tires of life." The same could be said of litigation. What I love most about being a lawyer is "getting it right," by obtaining the best resolution available to my client under the law, whether that means recognizing the value of compromise or recognizing the value of a principled stand.

When I'm not practicing law, I'm instructing classes as a Black Belt in Brazilian Jiu-Jitsu. The mindfulness of drilling and the intensity of sparring are two modes in which I feel most fully human and alive. I also dabble in non-legal writing and have a podcast. Don't ask me about it, I'll tell you.
