Former prosecutors. Now your strongest defense.
We spent years building these cases for the State. Now we use everything we learned to protect people like you.

Ktenas Law is a DUI and criminal defense firm serving Cook, Will, and DuPage counties. Our three attorneys are former Illinois prosecutors who defend DUI charges, gun charges, drug cases, theft, and violent crime charges.
For over a decade, Ktenas Law has defended people across Cook, Will, and DuPage counties. Alex, Nick, and Lauren each spent years as prosecutors before they ever defended anyone.
That is the whole point. We know how the State decides what to charge, which evidence it leans on, and where it gets careless. That holds true for a first DUI, and just as true for a gun or drug case.
As the founder of Ktenas Law, Alex Ktenas brings the insight of a former prosecutor to every defense strategy. Having served as an Assistant State's Attorney in both Chicago and Markham, Alex spent years building cases for the government, giving him the unique ability to dismantle them for his clients today. A lifelong Chicagoan and President of the South Suburban Bar Association, Alex has successfully litigated hundreds of felony and misdemeanor trials across Cook County and surrounding counties. Recognized by Expertise as one of the Best DUI Lawyers in Chicago and by Super Lawyers as a rising star, Alexander Ktenas has spent years not only learning the specific statutes related to DUI defense but also spent countless hours learning and studying the National highway traffic safety administration guidelines on how police officers are required to investigate all types of DUI cases. This has helped Alexander's clients with great success as he has been able to secure victory for hundreds of clients by knowing the laws better than the other side. Alex has also been rated as a top rated local attorney in Chicago and has been consistently rated as a top 10 best attorney for multiple years running. He doesn't just know the law; he knows the specific judges, prosecutors, and procedures that will determine the outcome of your case.
Nicholas Ktenas brings a level of forensic precision to DUI defense that few attorneys can match. A Magna Cum Laude graduate of Northern Illinois University College of Law, Nick finished in the Top 10 of his class, a distinction that reflects his relentless attention to detail. Before entering private practice, Nick served in the Cook County State's Attorney's Office (Felony Division in Markham), where he gained the "insider" perspective on how the State builds its cases. Today, Nick utilizes that prosecutorial background to dismantle DUI charges from the inside out. Known for his methodical approach to evidence, auditing everything from officer field notes to breathalyzer logs, Nick is the strategist you want when the outcome depends on the fine print. Recognized as a "Rising Star" by Super Lawyers, Nick represents the new standard of precision in Illinois criminal defense.
Lauren Ktenas completes the firm's "prosecutorial trifecta." As a former Assistant State's Attorney, Lauren spent years inside the system, making decisions on how to charge and prosecute everything from traffic offenses to complex felonies. She brings a disciplined, strategic mindset to the defense table, using her intimate knowledge of the State's internal procedures to find the weaknesses in their case that others miss. While she is known for her tenacity in the courtroom, Lauren is equally recognized for her ability to guide clients through the chaos of the legal system. She specializes in deconstructing the "investigative" phase of a DUI, analyzing how the initial charges were filed and whether the police followed strict protocol. When you need a defense that is as calculated as it is aggressive, Lauren Ktenas delivers.

Being charged with something does not make you guilty of it. Most cases have weak points, and most people never find out where they are.
Finding them is our job, not yours.
You will get straight answers about what you are facing, what can realistically be done about it, and what it costs. We read every page of the police report, check whether the testing was handled correctly, and look hard at whether the stop was lawful to begin with. If something does not hold up, we say so in court. That is the same work whether the charge is a DUI, a gun case, or a felony.
Our attorneys used to build these cases for the State, both DUI and criminal. We know where police reports go thin, when test results will not hold up, and how the prosecutors and judges in each courthouse actually work.
We spot the errors in the police report that others miss.
We move fast on license suspensions and bond conditions.
We negotiate from strength because the State knows we are ready for trial.
Did police have a lawful reason to stop, search, or detain you? If they did not, the evidence that came after it may not be allowed in. We review the footage closely.
Was there probable cause to arrest you at all? Were you read your rights, and was anything you said taken down properly? These answers decide what a prosecutor is actually allowed to use against you later on.
Breath machines, blood draws, and lab work all follow strict rules. We pull the records for the equipment used in your case and check them.
Police and prosecutors have to follow set steps, from how a test is timed to how evidence is logged and handed over. When a step gets skipped, that matters, and we make sure the court hears about it.
After a failed or refused test, the Statutory Summary Suspension (625 ILCS 5/11-501.1) takes effect on day 46. A Petition to Rescind (625 ILCS 5/2-118.1) lets your attorney fight it before it starts.
Write down the stop, the tests, the timeline.
Talk to no one about the case but your lawyer.
Count 46 days from your notice. Do not miss it.
Citations, bond slip, and the suspension notice.
Have an attorney assess the stop and the testing.
A first offense DUI in Illinois is a high stakes encounter for professionals with everything to lose. Despite being a misdemeanor, the consequences including a mandatory Statutory Summary Suspension can derail your career. At Ktenas Law, we take a first offense as seriously as you do. We challenge the reasonable suspicion for your initial stop and the probable cause for your arrest. By auditing the twenty minute observation period and breathalyzer calibration logs, we aim to suppress evidence and secure a dismissal to ensure one mistake does not define your future.
Read moreWhen facing a second or third DUI, the State attorney shifts from rehabilitation to retribution. These cases carry mandatory jail time and long term license revocation. Defending multiple offenses means taking apart how the State is using your prior record against you. We deep dive into the technicalities of the current arrest while simultaneously evaluating the validity of past convictions. Our approach focuses on motion to suppress strategies, challenging the chemical testing accuracy and officer testimony to prevent the devastating repeat offender labels that trigger mandatory incarceration.
Read moreCharges involving a fatality are the most severe in the Illinois Vehicle Code, often carrying non probationable prison sentences. These cases need more than a lawyer; they need careful forensic work. We collaborate with independent accident reconstruction experts and toxicologists to challenge the State narrative. Whether it is disputing the proximate cause of the accident or exposing flaws in the forced blood draw procedures, our defense is built to answer the emotional weight of the prosecution with cold hard scientific facts. In high stakes litigation, precision is your only protection.
Read moreFor commercial drivers, the legal limit is not 0.08, it is 0.04, and a conviction means a lifetime disqualification. A CDL is your most valuable asset, and the State Zero Tolerance policy leaves no room for error. We specialize in the complex intersection of Illinois traffic law and Federal Motor Carrier Safety Administration regulations. We fight both the criminal charge and the administrative suspension. By scrutinizing the specific nuances of commercial vehicle stops and chemical testing protocols, we work to save your career from a permanent major violation mark.
Read moreA DUI becomes a felony based on specific aggravating factors like driving without a license, multiple priors, or accidents involving injury. This elevates the case to a Class 4 felony or higher. We attack the aggravating elements of the charge to de felonize the case. Our defense involves a careful audit of the State paperwork and procedure. By challenging the underlying basis for the felony enhancement, we aim to reduce charges to misdemeanors or secure total acquittals, shielding you from a permanent felony record and prison time.
Read moreIllinois Zero Tolerance laws mean any trace of alcohol can result in a license suspension for a minor. For students and young professionals, the stigma of a DUI can jeopardize college admissions and future employment. We provide a protective, aggressive defense that focuses on the legality of the police interaction. Were the minor rights violated during questioning? Was the portable breath test administered correctly? We fight to keep these mistakes off a permanent record, utilizing diversion programs and evidentiary challenges to ensure a lapse in judgment does not derail a lifetime of potential.
Read moreDUI drug cases are notoriously flawed because presence in the system does not equal impairment behind the wheel. Unlike alcohol, there is no universal limit for many controlled substances. We use independent toxicology to test the State expert witnesses. Whether the charge involves cannabis, prescription meds, or narcotics, we expose the gap between a positive blood test and actual driving capability. By deconstructing the Drug Recognition Expert evaluation which is often highly subjective, we take apart the claim of impairment with real science.
Read moreIn Illinois, just paying the ticket is an admission of guilt that adds points to your record and spikes insurance premiums. For those with a CDL or a high profile career, even a speeding ticket is a threat. We handle petty and misdemeanor traffic offenses including aggravated speeding and reckless driving with the same intensity as a DUI. We scrutinize radar and lidar calibration records and officer positioning to beat the ticket in court. Our goal is to avoid supervision and seek outright dismissals to keep your driving abstract pristine and your insurance rates low.
Read moreA Reckless Driving charge is often the primary strategic target when fighting a DUI. While still a serious Class A misdemeanor, securing a reduction from "Driving Under the Influence" to "Reckless Driving" can save your license from the mandatory revocation that comes with a DUI conviction. In Illinois, this negotiation is high-stakes; the prosecution requires substantial leverage to agree to a reduction. Our team generates this leverage by exposing flaws in the chemical testing or field sobriety procedures. We pursue this outcome to keep a drunk driving record off your name, and to protect your driving privileges and insurance rates from a full DUI conviction.
Read moreFor doctors, nurses, lawyers, and CPAs, a criminal charge triggers an immediate threat from the IDFPR. We do not just handle the courtroom; we handle the board room. We work to keep your professional license protected during and after the criminal proceedings. We coordinate your defense strategy to satisfy reporting requirements while minimizing the risk of suspension or revocation. We defend your livelihood on both fronts at once, with the care your career deserves.
Read moreIn Illinois, carrying a firearm while under the influence is a Class A Misdemeanor that immediately jeopardizes your Second Amendment rights. Under the Concealed Carry Act, your license is rendered invalid the moment you are deemed impaired, effectively treating you as unlawfully armed. This creates a dual crisis: the threat of up to one year in jail and the immediate revocation of your FOID card and Concealed Carry License (CCL). At Ktenas Law, we defend this specific overlap of DUI and gun law. We challenge the prosecution’s proof of impairment to prevent a conviction that strips you of your ability to legally own or carry a firearm forever.
Read moreA criminal charge in Cook County follows you long before any verdict does. It shows up in background checks, in job applications, and in conversations you should not have to have. Most people arrested for the first time have no idea what happens next, and that uncertainty is often worse than the charge itself. We defend felonies and misdemeanors across Cook, Will, and DuPage counties, and we start by telling you plainly what you are facing and what your realistic options are. Every case gets the same first step: a close read of how police built it, and where it does not hold together.
Read moreIllinois has some of the strictest firearm laws in the country, and the rules change often enough that people who believed they were following them still get arrested. An aggravated UUW charge is a felony, and a conviction ends your FOID card and your concealed carry license along with it. We defend UUW, unlawful possession, and FOID related charges throughout the Chicago area. These cases frequently turn on whether the stop and the search were lawful in the first place, which is exactly the ground where a case can be won before it ever reaches a jury.
Read moreIllinois separates simple possession from possession with intent to deliver, and the difference between them can be the difference between probation and prison. That line is often drawn by how police interpreted what they found, not by anything you actually did with it. We defend possession, intent, and trafficking charges, and we look first at how the search was conducted and whether the evidence was handled properly from the roadside to the lab. For eligible clients we also pursue diversion and treatment based outcomes that keep a conviction off your record entirely.
Read moreIn Illinois, the value of what was allegedly taken decides whether you are facing a misdemeanor or a felony, and that threshold is lower than most people expect. Retail theft over three hundred dollars can be charged as a Class 3 felony, and a prior conviction can turn even a small amount into a felony on its own. We defend retail theft, burglary, criminal damage, and related property charges. These cases often rest on identification, intent, or the value assigned to the property, and all three are open to challenge.
Read moreAn order of protection can remove you from your home, restrict contact with your children, and cost you your firearm rights, and it can be entered on far less evidence than a criminal conviction requires. Many people do not realize how much is at stake until the hearing is already underway. We represent clients on both sides of these petitions across Cook, Will, and DuPage counties. Because these hearings move quickly and the record you create in them can follow you into a related criminal case, getting the first hearing right matters enormously.
Read moreFraud, embezzlement, and financial crime investigations usually begin long before anyone is charged, which means the most important decisions often get made before you have a lawyer. What you say to an investigator early can shape the entire case against you. We defend financial crime allegations and work alongside your professional obligations, not against them. These cases are built on documents and paper trails, so the defense is built the same way: reconstructing what the records actually show, rather than what the State assumes they show.

A DUI arrest in Chicago triggers two separate cases: a criminal charge in Cook County court and a civil Statutory Summary Suspension of your license through the Illinois Secretary of State. The suspension takes effect on the 46th day after notice, so acting quickly gives your attorney the best chance to challenge it. A first offense may also be eligible for court supervision.
Illinois law sets the legal limit at a blood alcohol concentration of 0.08% for most drivers under 625 ILCS 5/11-501. Commercial drivers face a 0.04% limit, and drivers under 21 fall under the state's zero tolerance law. You can also be charged below 0.08% if the State claims impairment.
Not automatically, and not immediately. A failed or refused chemical test triggers a Statutory Summary Suspension that begins on the 46th day after notice. Your attorney can file a Petition to Rescind and request a hearing to challenge the suspension before it starts. If a suspension does take effect, you may still qualify for a restricted driving permit.
You will be given a court date, and in many cases released on conditions rather than held. The first hearing is the arraignment, where the charge is read and a plea is entered. Between the arrest and that date, the State is still building its case, which is exactly why it helps to have an attorney reviewing it early.
No. A first DUI in Illinois is a Class A misdemeanor, punishable by up to 364 days in jail and fines up to $2,500. A DUI becomes a felony, called aggravated DUI, when factors like multiple priors, driving without a valid license, or an injury accident are involved.
Yes. Courts dismiss charges when the evidence does not hold up. Common grounds include an unlawful stop or search, no probable cause for the arrest, field sobriety or calibration errors, and procedures that were not followed. Whether dismissal is realistic depends entirely on the facts and the evidence in your particular case.
Usually yes. Aggravated unlawful use of a weapon is typically a Class 4 felony, carrying 1 to 3 years and the loss of your FOID card and concealed carry license. Many of these cases turn on whether the stop and the search that produced the firearm were lawful, which is often where the strongest defense is found.
Fees depend on the complexity of the charge, your record, and whether the case goes to trial. A DUI conviction often costs far more over time through fines, insurance increases, and lost work opportunities. We offer a free case review so you can understand the stakes and your options before making any decision.
