Dealing with Criminal Charge(s) in DuPage County

‍

You made a decision that went wrong.

‍

Maybe you were in the wrong place at the wrong time. Maybe it was a misunderstanding with police. Maybe it was an honest mistake.

‍

Regardless, you were handcuffed, processed at the station, and thrown into a confusing legal system. Now, you're facing criminal charges that could change your life forever.

‍

When you face a criminal charge, you may feel worried, overwhelmed, and scared. Your mind may race with questions. You may ask:

‍

• Will I go to jail?
• Will I lose my job?
• What about my family?
• Will I still be able to provide for my loved ones?

‍

Above all else, you might wonder if a single mistake should define who you are and erase all the good you've done throughout your life.

How We Help

‍

Hi, I'm Mike McMahon.

‍

As a DuPage County criminal defense attorney and former prosecutor, I’ve stood by over a 1,000 clients who’ve been exactly where you are now.

‍

I know exactly what you're feeling. It's overwhelming, confusing, and frightening. But here's a truth that should bring you some hope:

‍

‍Most criminal cases have weaknesses. Police mistakes. Evidence problems. Rights violations. Finding these issues can change your case outcome—sometimes getting charges reduced or even dropped.

‍

I know how to find these weaknesses because I used to build cases for the prosecution. I know their playbook and where they typically make mistakes.

‍

Judge Cary Pierce served on the DuPage County bench for 20 years. He knows how judges decide cases like yours and which arguments work in court.

‍

When we find problems with your case, we know exactly how to use those issues to help you. We might get reduced charges or sometimes get charges dropped completely.

‍

Our experience on both sides of the system gives you an advantage most defense attorneys can't offer. We've helped thousands of clients get better outcomes than they thought possible.

‍

Now we're ready to fight for you.

‍

Attorney Michael McMahon, Former Prosecutor

‍

Before founding McMahon Law Offices, Michael McMahon spent over ten years as a DuPage County prosecutor. During that time, he:

‍

• Built and tried hundreds of criminal cases

• Learned exactly how police gather and process evidence

• Discovered the common mistakes officers make during arrests

• Developed relationships with judges and courthouse staff

• Mastered the local court procedures in DuPage, Kane, and Cook counties

‍

Today, Michael uses this insider knowledge to defend people facing criminal charges. He can spot problems with evidence, police procedures, and constitutional rights that other attorneys might miss.

‍

"I know how prosecutors think because I was one," says McMahon. "I know what evidence they need to win and where they often fall short. That knowledge is now my clients' greatest advantage."

‍

• Presided over thousands of criminal cases

• Determined which defense arguments were effective

‍

Judge Pierce brings an unmatched perspective to your defense. He understands how judges think, what arguments they find persuasive, and how to present your case in the most favorable light.

‍

"Having spent over two decades on the bench, I've seen what works in a courtroom and what doesn't," says Judge Pierce. "I know which defense strategies persuade judges and which fall flat. That insight is invaluable when your freedom is at stake."
