- My clients hire me to take on their problems and solve them
- Having tried nearly 50 cases to jury verdict brings an intensity and focus to my work that is reflected in the exceptional preparation and great care I take with every case and client

- That knowledge is commonly reflected in higher settlement offers in cases where defendants know the attorneys are not too intimidated to show up at trial
- I am not afraid, and I will always show up
- My motto is simple: “I’m nice, until I’m provoked.” In practice, if my opponents treat me, my team, and our clients with respect, they will happily get the same in return
- If that practice ever changes, I will forever maintain my composure, but I will not tolerate incivility, and there will be measurable consequences
- Everyone deserves to be treated with dignity, and I will ensure that result
- I am not satisfied until justice is served—whether that takes weeks or years, and whether it happens through a settlement or a jury trial
