About Me

My practice is limited solely to serious personal injury. I have been chosen at Trial Lawyer of the year three times by the CCTLA. The most recent years have been 2005 and 2007. I have served as President for the local trial lawyers association for two years. I care about my clients and work very hard to serve their best interests. I believe in being involved in the community and have served on numerous boards and am the Mock Trial coach for a local high school. I believe that honesty and compassion are important in my profession. The majority of my clients are sent to me on referral by other attorneys and former clients. I limit the number of cases I accept so I can do the best job possible for my clients.
