About Me

  I offer over a decade of criminal law trial experience to serve the men and women of the United States military. Upon my graduation from law school with honors in 2001, I spent over five years as an attorney at the Kane County State’s Attorney’s Office where I handled thousands of criminal cases. 


In 2006, I joined the Air Force JAG Corps. I received high marks as a prosecuting attorney. The Judge Advocate General of the Air Force then chose me to become a military defense attorney. Despite glowing reviews and a promotion to Major, I decided to leave active-duty to become a civilian defense lawyer.


I now serve those serving America as a military defense lawyer and court-martial attorney. I currently live in Colorado with my family.
