Dui and Criminal Defense Attorney in Crystal Lake and Algonquin, IL

Protecting Your Rights, Your Record, and Your Future


A criminal charge can change everything. Whether it’s a first-time DUI or a more serious offense, the consequences can be life-altering—fines, jail time, license suspension, or a permanent mark on your record. But one charge does not define who you are. At William Hellyer Ltd Attorneys At Law, we help individuals across Crystal Lake, Algonquin, and nearby communities fight criminal charges with confidence and clarity.

With over four decades of courtroom experience, we understand the law—and how to navigate the local court system effectively. Most importantly, we treat you with the respect and attention you deserve. Because when you’re facing the weight of the criminal justice system, you shouldn’t have to face it alone.

Strong Defense for DUI And Criminal Charges


Being accused of a crime is frightening, especially if you’ve never had legal trouble before. You may be unsure of your rights, uncertain about your options, and afraid of what comes next. That’s where we come in.

We provide strategic defense services for a range of charges, from traffic violations to felony offenses.

DUI (Driving Under the Influence)

Illinois takes DUI offenses seriously—even a first offense can lead to license suspension, fines, mandatory counseling, or even jail. Penalties increase with repeat offenses, high BAC levels, or aggravating factors.

We defend against DUI charges by:

  • Challenging the legality of the traffic stop
  • Reviewing the accuracy of breathalyzer and field sobriety tests
  • Identifying procedural errors by law enforcement
  • Negotiating for reduced penalties or alternative sentencing

Our goal is to protect your driving privileges, minimize the legal impact, and help you move forward with your life.

Misdemeanors and Felonies

From shoplifting and disorderly conduct to drug possession or assault, we handle a wide variety of criminal charges. The consequences of a conviction—even for a misdemeanor—can affect employment, housing, and your reputation.

We defend against:

  • Theft and burglary
  • Drug charges (possession, intent to distribute)
  • Assault and battery
  • Domestic violence
  • Criminal damage to property
  • Weapons offenses

No matter the charge, we believe every client deserves a vigorous defense and a fair shot at justice.

Driver’s License Reinstatement & Traffic Offenses

In addition to DUI cases, we also assist with:

  • Suspended or revoked licenses
  • Traffic violations (speeding, reckless driving, driving without insurance)
  • Secretary of State hearings for license reinstatement

Losing your license can disrupt your job, your family, and your freedom. We help you take the necessary steps to restore your driving privileges legally and efficiently.
