Areas of Practice
Criminal Law
NEW PHONE NUMBER! (815) 545-7775 Phil has spent more than 45 years as a criminal attorney. His 15-years as a prosecutor gives him a unique perspective in crafting successful criminal defenses. If you have been arrested for a criminal offense in McHenry County, call Phil.
Personal Injury
Phil has successfully sued on behalf of innocent people who have suffered devastating injuries due to other's negligence. If you are not represented by a lawyer, you are likely to be taken advantage of. Moreover, there's no reason not to hire a lawyer; injury cases can be handled on a contingency fee basis, meaning there is no legal fee unless money is awarded to you.
Felonies & Misdemeanors
Decisions by police to charge a felony or misdemeanor are oftentimes done with scant evidence, perhaps late at night, and without all the information. Over charging is common. This is why you need an experienced lawyer like Phil who is familiar with the personnel and justice system in McHenry County.

Do you need a lawyer?
​
Does your issue involve the law? Does the other party have a lawyer? Could you lose your rights or your freedom if you don't have a lawyer?
​
If you answered 'Yes' to any of those questions, you definitely need a lawyer.
What kind of lawyer do you need?
​
Finding the right lawyer is critical to your success. Is the lawyer experienced in your issue? Is the lawyer familiar with the local courts and their procedures? What approach will the lawyer take?
​
These are all important questions to ask your next attorney.
Am I the right lawyer for you?​
With over forty-five years of experience, I've tried and won cases from traffic tickets to murder and worked both sides of civil disputes.
​
You'd have a hard time finding another lawyer in McHenry County with the breadth and depth of my experience. But having said that, if I am not
the right attorney for the job, I will gladly refer
you to another lawyer better qualified to serve your interests.
