Why did you become a lawyer?

I became a lawyer because I believe in the importance of the rule of law and how that core tenet differentiates the United States from many other countries. I am passionate about my work because of the clients I represent. The increasing scope of government regulation touching many aspects of business activity has created a situation where more law-abiding businesses and individuals find themselves targeted in regulatory and law enforcement investigations initiated by aggressive regulators and prosecutors. This can be an overwhelming and frightening situation for clients. I strive to give them the best possible reputation while simultaneously helping them manage the pressure of dealing with an ongoing government investigation or lawsuit.

What do you do outside of work?

I travel as much as I can. I have been to six of the seven continents with only Antarctica left on the list. I recently traveled to Egypt, South Africa, and Greenland. I enjoy learning about diverse cultures, cooking, and perfecting my smoked brisket skills. I am a beekeeper, maintaining several hives at my Hill Country of Texas home. I also enjoy watching and following many forms of motorsports, particularly Formula One, IndyCar, and Moto GP.
