About me

I have tried criminal felony cases in Kane, Kendall, La Salle, Will, Du Page and Cook County.  In 2011 I co-counseled a First Degree Murder Trial at 26th & California and my client was found not guilty.  I also conducted an Armed Robbery bench trial and my client was found not guilty.  I co-couseled a Possession of a Controlled Substance With Intent to Deliver (56 pounds of marijuana) in front of a jury in Ottawa, Illinois, La Salle County and the jury found my client guilty. 

I have defended numerous clients in Driiving Under the Influence from preliminary matters to trial.

I am on call 24 hours a day, 365 days a year.  My cell phone number is listed above.  If you need representation - I will be there.  Discount fees for military veterans. I am a Vietnam Vet - 101st Airborne - 1969-1970.

I  have owned, buiilt and ridden Harley-Davidsons for 40 years.  I currently own and ride a 1998 Softail Springer.
