About me

CALL: (913) 782-7072 for a FREE CONSULTATION.

I have been practicing law in Kansas and Missouri for over 30 years.  I have dedicated my practice to helping people in need.  Whether it be aggressively defending someone accused of a crime, or representing someone that has suffered a serious injury to themselves or a loved one, I am the lawyer who goes in front of the jury and asks for justice.   

When individuals call my office to talk to me about their criminal case, or a personal injury claim they may have, I listen to what they have to say, and explain what their rights are.  Often times, they don’t fully understand the charges against them, or for a personal injury case, the damages they are entitled to.  But for every call, I take the time to listen, and respond to their questions in a meaningful way.
