About me

I have practiced law for nearly 20 years. I am licensed in Missouri, Kansas and Colorado. The majority of my practice deals with criminal defense with a focus on drunk driving defense. 


I handle cases from the first time offender to serious felony cases.  I emphasize working with the client to help them understanding the law and how it applies to their situation. 


I aggressively fight to protect my clients rights and privileges. I will defend my clients through a trial if necessary.
