For over a decade, as Ktenas Law, we built a reputation for aggressive advocacy. But as our focus narrowed, our mission became clear. We realized that DUI defense in Illinois has become too complex for "general" practitioners.
Scientific methods evolve. Laws change. Police officer training and policies shift. We are known as Chicago DUI Lawyers because that is exactly what we do. We focus 100% of our energy, resources, and training on one thing: Beating DUI charges in Cook County and surrounding areas.

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.

When you need a defense that is as calculated as it is aggressive, Lauren Ktenas delivers. read more

Most law firms are "General Practitioners." They handle divorces on Monday, real estate on Tuesday, and a DUI on Wednesday.
We believe you deserve better.
If you were facing a life-threatening medical diagnosis, you wouldn't look for the "cheapest" doctor or a generalist, you would find a specialist. Think of us as the Neurosurgeons of DUI Defense. We provide the surgical precision required to deconstruct forensic evidence, audit breathalyzer software, and dismantle the prosecution's case.
Our team includes former prosecutors who used to build DUI cases for the state. We know exactly where the police cut corners. We know when a breathalyzer result is weak. We know which judges in the Daley Center are tough, and which are fair.
We spot the errors in the police report that others miss.
We challenge the suspension of your license immediately (MDDP/BAID).
We negotiate from strength because the State knows we are ready for trial.
Did the officer have a valid reason to pull you over? If the stop was illegal, the evidence is inadmissible. We review the dashcam footage frame-by-frame.
Did the officer have probable cause to arrest you in the first place? Were you read the miranda warnings upon arrest? We review all the intricacies of the law to put our clients in the best position to win their case.
Breathalyzers are machines, and machines break. We audit the calibration logs of the specific device used in your arrest.
Did they read you the Warning to Motorists correctly? Did they observe you for 20 minutes before testing? Did the officers follow the National Highway Traffic Safety Administration guidelines? We find the procedural flaws.
Mediocrity is not an option in a life-altering legal crisis. Secure a powerhouse defense that combines former prosecutor insight with years of experience to deliver the real results your reputation demands.
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 Chicago DUI Lawyers, we treat a first offense with surgical precision. We aggressively 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 requires an elite strategist who can dismantle the prosecution's reliance on your prior record. We deep dive into the technicalities of the current arrest while simultaneously evaluating the validity of past convictions. Our aggressive 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 require more than a lawyer; they require a forensic powerhouse. 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 elite defense is designed to counter 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. Our firm aggressively fights 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 relentless audit of the State paperwork and procedural errors. 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 utilize elite toxicological analysis to challenge 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 dismantle the prosecution claim of impairment with scientific rigor.
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 aggressively pursue this outcome to avoid the permanent stigma of a drunk driving record, protecting your driving privileges and insurance rates from the devastating fallout of 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. Our white glove defense ensures that your professional license is 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 serve as the premier shield for your livelihood, providing a dual track defense that covers every front with the surgical precision your career demands.
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 Chicago DUI Lawyers, we specialize in defending this specific intersection of DUI and gun laws. We aggressively 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.
