Third Coast Lawyers is a woman and minority owned personal injury law firm licensed in Wisconsin, Illinois, and Missouri, with a nationwide network of attorneys. The firm specializes in toxic exposure and medically intensive injury claims where expert medical causation proof determines the outcome.
Founded by Anna O’Connor, a trial attorney with extensive experience trying jury cases across state courts, federal, and multi-district proceedings, Third Coast Lawyers serves personal injury and toxic exposure victims throughout the Great Lakes region, with the capacity to co-counsel complex cases nationwide.
The firm also handles defective medical devices, medical malpractice, wrongful death, car accidents, sexual assault, and on-the-job injuries. From day one, Third Coast Lawyers locks in the timeline, identifies responsible parties, and maps the records needed to move the case forward while evidence is still available.
If your situation involves serious injury, documented exposure, or a fatality, contact Third Coast Lawyers for a free consultation. We do not charge attorney fees unless there is a recovery.
Evidence & Documentation
The records that decide most personal injury claims in Wisconsin, Illinois, and other jurisdictions are medical documentation, incident reports, and a dated exposure or treatment timeline assembled early — before evidence disappears.
Exposure timeline, medical records, plus work history or jobsite records. Expert medical causation review is required to connect exposure to diagnosis.
Police report plus scene photos. Medical bills and lost wages form the foundation of the damages calculation.
Hazard photos plus incident report details. Store video request timing is critical — footage is often overwritten within days.
Full chart review plus expert screening. A causation proof plan must be established before the claim can proceed.
Pharmacy history plus prescribing records. Warning and label analysis establishes whether the manufacturer withheld known risks.
Device identifiers plus operative notes. Recall and adverse event timeline links the specific device lot to documented harm.
What We Handle
We build an evidence-backed case file that supports negotiation and, if needed, litigation — starting with timelines, records, and preservation steps.
Exposure-driven illness, asbestos, jobsite contamination, industrial chemical exposure, and environmental release claims. Medical causation proof is the center of every case.
Medication harms, failed warnings, and prescribing record analysis. Includes cases where a manufacturer withheld known risks or a prescriber deviated from the standard of care.
Device identifiers, operative notes, recall timelines, and adverse event documentation. Covers implant failures and recalled hardware tied to a specific device lot or manufacturer.
Chart review, expert screening, and causation analysis for surgical errors, diagnostic failures, and hospital-acquired harm where the standard of care is disputed.
Estate authority, loss documentation, and claim deadlines. Includes cases where a surviving family member must establish standing before evidence or claim windows close.
Police reports and scene documentation as the foundation of the proof file for collision claims, combined with medical billing and lost wage records.
Jobsite liability and federal regulatory frameworks, including FELA claims for railroad workers injured in the course of employment.
Premises liability documentation and incident report timing for property hazard claims. Hazard photos and video preservation are time-critical.
Privacy-first communication and sealed filing options where available. Sensitive matters are handled with strict confidentiality throughout the process.
Building an evidence-backed case file that supports negotiation and, if needed, litigation starts with timelines, records, and preservation steps secured as early as possible. Cases handled through this process reach negotiation with a complete, documented proof file that gives clients the strongest possible position before a single demand letter is sent.
Toxic Exposure Claims
Toxic exposure cases in Wisconsin, Illinois, Missouri, and other Great Lakes jurisdictions turn on two things: a documented exposure timeline and expert medical causation proof connecting that exposure to a confirmed diagnosis.
Whether the source is a contaminated jobsite, a building water system, an industrial chemical, or an environmental release, the claim requires records establishing what you were exposed to, for how long, and what harm resulted.
Under federal CERCLA standards and applicable state tort law, responsible parties include employers, property owners, manufacturers, and governmental entities.
Wisconsin: Personal injury claims are subject to a three-year statute of limitations under Wis. Stat. 893.54.
Illinois: A two-year deadline applies under 735 ILCS 5/13-202.
Missouri Statue of Limitations
In toxic exposure cases, the clock may start at the date of diagnosis rather than the date of exposure — making early legal review essential in every matter.
Process: Intake to Resolution
Every case follows a disciplined, evidence-first process — from the first call through final resolution.
1
We review the facts, identify the type of claim, and explain the legal framework that applies. No charge, no obligation.
2
We immediately identify and secure time-sensitive evidence — scene photos, surveillance footage, medical records, and exposure documentation — before it disappears.
3
We build the complete proof file: responsible parties, applicable statutes, expert medical causation review, and a documented timeline of harm.
4
With a complete, documented case file, we present a demand to the responsible parties and negotiate from a position of strength.
5
If a fair settlement is not reached, we file suit and take the case through state, federal, or multi-district proceedings.
6
Whether through settlement or verdict, we pursue the maximum recovery available under the law. You pay nothing unless we win.
The First 14 Days
The decisions made in the first two weeks after an injury or exposure event have a disproportionate impact on the strength of the final claim.
1
The first task is establishing a precise, dated record of the injury or exposure event. Gaps in the timeline are the most common reason claims fail at the causation stage. We document everything from day one.
2
In complex claims — toxic exposure, defective devices, multi-vehicle crashes — more than one party may bear legal responsibility. Early identification prevents missed defendants and preserves all recovery options.
3
Surveillance footage is overwritten in days. Medical records can be amended. Jobsite logs disappear after inspections. The first 14 days determine what evidence exists to build the case — and what is lost forever.
If you are reading this within 14 days of an injury or exposure event: contact Third Coast Lawyers today. The consultation is free, and the steps we take in the first two weeks can determine whether a strong case is possible.
Evidence Checklist
You do not need everything on this list to schedule a consultation. But the more you can bring, the faster we can assess the strength of your claim and identify what additional records need to be preserved.
Special Note: Exposure-Related Illness
If your claim involves toxic exposure or an occupational illness, the most important document is a written diagnosis from a treating physician that identifies the condition. Without a confirmed diagnosis, the causation chain cannot be established. If you have not yet received a formal diagnosis, we can help identify the right medical specialists and guide the documentation process.
