About Me

I have been practicing law for over 33 years.  Throughout my career I have handled personal injury and wrongful death cases.  I find helping people in that field of practice to be very rewarding.  I also did criminal defense work up until about 2005, which provided invaluable trial and appellate experience that has translated well over into my current civil-only personal injury/wrongful death practice.  


In my leisure time over the years I have enjoyed family, fishing, camping, sports, coaching basketball, soccer, and mock trial, reading novels and history, and, most recently, learning to speak and read Spanish.
