Since 1996
Why did you become a criminal defense lawyer?

- California Western School of Law in San Diego
- Pepperdine University for my MBA
- The University of Arizona for my BS in business administration

I don’t know how other lawyers conduct themselves all the time but I try to assist the client through even the smallest aspects of their case that could prove to be important to them in the end.
What do you like most about your job?
Helping someone get justice for their situation.
What do you do when you aren’t a lawyer?
I’m a sports nut so I’ll watch all my teams. Spending time with friends. Riding my Harley.
What questions do clients most commonly ask you? What’s your answer?
The one question I frequently get asked is “Could I have obtained the same result without hiring you?” My answer has always been “Maybe.” That’s because the law sometimes works simply but more often is highly complicated which necessitates the experienced professional.

Practicing law is not how it is portrayed on television.

Meet them personally and ask them how their relationship is with the corresponding prosecution agency.

Even before going to law school do several internships in areas that interest you. It may narrow your decision or perhaps change your perspective on becoming an attorney.
What is your greatest strength?
My ability to keep my emotions in check. I feel that’s the best thing an attorney can do for their client. Not to be confused with a lack of passion for the client’s cause.
What questions should a client ask to hire the right lawyer?
- Am I hiring an attorney to represent me and achieve the best outcome we can negotiate or am I hiring someone to get me the result of my choosing?
- Are you experienced in the area of law where my situation rests?
- How familiar are you with our adversary?
