Chicago Medical Malpractice Lawyer
When a doctor, hospital, or nurse falls below the accepted standard of care and you are seriously harmed, the consequences can change your life and your family's future. At Ori Law Group, both Joe and Kristen Ori concentrate in medical malpractice, and Kristen leads our litigation with a focus on the medical evidence that decides these cases. We represent patients and families across Chicago and Cook, DuPage, Will, and Kane Counties, and we have recovered more than $150 million for injured clients — including eight-figure medical-negligence results.
When you trust a doctor or hospital with your care, you expect competence and attention. Most providers deliver it. But when a provider falls below the accepted standard of care — misreading a scan, missing a diagnosis, mishandling a delivery, or administering the wrong medication — the harm can be permanent. Medical malpractice is a core practice at Ori Law Group, and we represent patients and families across Chicago and Cook, DuPage, Will, and Kane Counties who have been seriously injured by negligent medical care.
These cases demand more than sympathy; they demand command of the medicine. Both Joe and Kristen Ori concentrate in medical malpractice, and Kristen leads our litigation with a focus on medical evidence. She reads the chart the way the defense will, identifies the entries that were missed, and reconstructs the treatment timeline that shows when a careful provider should have acted differently. Illinois requires a written report from a qualified physician confirming a reasonable and meritorious basis before a malpractice suit can be filed under 735 ILCS 5/2-622, and we build toward that standard from the first record review.
We pursue the full picture of liability. A serious injury often involves more than one provider — a physician, a nurse, a laboratory, and the hospital itself can each bear responsibility, whether for an individual error or for institutional failures like understaffing or inadequate protocols. We identify every party whose negligence contributed to the harm, develop the expert testimony on standard of care and causation, and prepare each case to be tried, not merely settled. Illinois law sets firm deadlines — generally two years from discovery, with a four-year outer limit and special rules for injured children — so the records and evidence are best preserved early.
If you believe you or a loved one was harmed by a medical provider’s negligence, contact Ori Law Group for a free, confidential consultation. We will review your records, explain your rights honestly, and tell you where we believe the medical evidence stands — with no upfront cost, and no fee unless we recover for you.
What to Do After Your Accident
- Continue following your treatment plan and seek care from a different, independent provider for your ongoing condition.
- Request a complete copy of your medical records, including imaging, lab results, and nursing notes.
- Write down your timeline — symptoms, appointments, what you were told, and by whom — while it is fresh.
- Keep every bill, prescription, and document related to your care and your injury.
- Do not sign anything from the hospital, provider, or its insurer without legal advice.
- Do not give a recorded statement to a provider's risk-management department or malpractice insurer.
- Note the dates of your treatment — the deadline to file a medical malpractice claim in Illinois can be shorter than you think.
- Talk to a medical malpractice attorney as early as possible, so the evidence and records can be preserved and reviewed.

Kristen leads a detailed review of the records, imaging, and treatment timeline to identify exactly where the care fell below the standard.

What Makes a Medical Malpractice Case
Not every bad medical outcome is malpractice. Medicine carries real risk, and a poor result alone is not proof of negligence. A medical malpractice claim in Illinois turns on four elements, and you must establish each one.
First, a duty: a provider-patient relationship that obligated the doctor, nurse, or hospital to care for you. Second, a breach: the provider deviated from the accepted standard of care — what a reasonably careful provider in the same specialty would have done in the same situation. Third, causation: that breach, rather than your underlying condition alone, was negligence that contributed to your injury. Fourth, damages: real harm and losses that flow from the breach.
Causation is often the hardest element to prove, because the defense will argue your existing illness or injury caused the outcome no matter what the provider did. That is where the medical evidence matters most — and where our focus on the records, imaging, and qualified expert review is built to meet the burden.
How Kristen Builds the Medical Evidence
Medical malpractice cases are won and lost on the medicine. Kristen Ori leads our litigation with a focus on medical evidence — reading the chart the way the defense experts will, finding the entries that were missed, and reconstructing the timeline that shows when a reasonable provider should have acted.
We gather the complete record, not the summary the hospital offers: physician orders, nursing notes, medication administration records, fetal monitoring strips, imaging, and lab data. We retain qualified physicians in the right specialty to review the care and, when the evidence supports it, certify the case under Illinois law.
Hospitals and Health Systems Can Be Held Accountable
Liability in a medical malpractice case is rarely limited to one person. A hospital can be responsible both for the staff it employs and for its own institutional negligence — understaffing, inadequate protocols, or failing to act on warning signs in the chart.
When several providers contributed to the harm — a physician, a nurse, and the hospital, for example — Illinois law allows claims against each. We identify every party whose negligence contributed to your injury so that no responsible party is left out of the case.

Frequently Asked Questions
What is an affidavit or report of merit, and why does my case need one?
Illinois law (735 ILCS 5/2-622) requires that a medical malpractice complaint be filed with an affidavit and a written report from a qualified health professional confirming there is a reasonable and meritorious basis for the claim. Without it, the case can be dismissed. We obtain this review early in our investigation, before suit is filed, so your claim rests on a sound medical foundation.
How long do I have to file a medical malpractice claim in Illinois?
Generally two years from when you knew, or reasonably should have known, of the injury, with an outer four-year statute of repose measured from the date of the negligent act (735 ILCS 5/13-212). Different deadlines apply to injured children, and claims against a public hospital can have a much shorter notice period. Because these deadlines are unforgiving, it is best to speak with an attorney as soon as you suspect negligence.
Is the deadline different for a child's injury?
Yes. The deadline for a child harmed by medical negligence is tolled, giving an injured minor more time to bring a claim, subject to a longer outer limit. Because the rules differ from an adult's, have a child's potential claim reviewed promptly so no deadline is missed.
What is my medical malpractice case worth?
It depends on the severity of the harm, your losses, and the medical evidence. Damages can include past and future medical care, lost earnings, the cost of long-term care, and pain, suffering, and loss of a normal life. After reviewing your records, we give you an honest assessment — not a guarantee.
How long does a medical malpractice case take?
These cases are thorough by nature. The required physician review must be completed before filing, and discovery and expert development take time. Many cases run a few years from intake to resolution. We move efficiently while building the case fully, because a rushed case is a weaker one.
Isn't a bad outcome from treatment automatically malpractice?
No. Medicine carries real risk, and a disappointing result alone is not negligence. A claim requires proof that a provider breached the accepted standard of care and that the breach was negligence that contributed to your injury. That is precisely what our medical-evidence review is designed to evaluate.
What does it cost to hire Ori Law Group for a malpractice case?
Nothing upfront. We handle medical malpractice cases with no upfront cost — you pay no fee unless we recover for you, and the costs of the required physician review and experts are advanced by the firm. Your consultation is always free.
Will Joe or Kristen personally handle my case?
Yes. As a boutique firm, you work directly with Joe and Kristen Ori from the first consultation through resolution. Kristen leads the medical-evidence work, and you are never handed off to a junior associate.
