About me

  Give me a call anytime to talk about your situaton, I do free consultations and offer free advice and referrals too!  I am dedicated to helping my clients whether it is a criminal charge, personal injury, legal dispute, family matter, or even just a traffic ticket.  I give me all to each of my clients and will fight hard to make sure their interests are protected.  I started out as a public defender and since then have worked with and learned from some of the best lawyers in criminal defense and personal injury.  


   I live in Mountlake Terrace with my wonderful wife.  We are expecting our first baby this summer and I can't wait to be dad.  We also have an amazing australian shepherd named Ace who loves to play frisbee in at the parks nearby. I love the Seattle area and look forward to raising a family here and hopefully teach my kids to be Seahawks and Sounders fans too.
