Brain Injury Attorney in Chicago
Former Fortune 500 Defense Attorney Now Fighting for Brain Injury Victims
A serious brain injury can change everything in a matter of moments. Memory, mood, speech, and balance can all be affected, and families often find themselves managing medical decisions, work disruptions, and an uncertain future at the same time. When that injury is connected to corporate negligence, toxic exposure, or a railroad incident, the legal issues become just as complex as the medical ones.
The Law Office of Gregory M. McMahon represents individuals and families facing these kinds of devastating injuries through its Chicago personal injury lawyer practice. The firm focuses on serious cases that often involve powerful companies and complicated science, approaching each matter with careful planning and a clear strategy. From the first conversation, the goal is to help clients understand what happened, what their options may be, and how to move forward.
Before founding this firm, attorney Gregory M. McMahon spent more than a decade defending Fortune 500 companies in high-stakes toxic tort litigation. He now uses that insider knowledge to pursue justice for injured workers and families, including those dealing with traumatic brain injuries. That rare perspective shapes every case decision, from early investigation through settlement talks or trial preparation.

Why Families Choose The Law Office of Gregory M. McMahon After a Brain Injury
Families coping with a brain injury need more than a generic personal injury practice. They need counsel who understands how large corporations evaluate risk, defend claims, and attempt to avoid responsibility for long-term harm. Attorney McMahon has seen those strategies from the inside, and he applies that understanding on behalf of the people those corporations once tried to minimize.
During his years as a corporate defense attorney, McMahon handled complex toxic tort matters for Fortune 500 clients involving technical medical questions, scientific experts, and detailed corporate records. That background is directly relevant when a brain injury is linked to chemical exposure, unsafe industrial processes, or railroad work, all of which require sophisticated proof of causation.
Corporate defendants in brain injury cases follow predictable patterns: they dispute causation, raise preexisting condition arguments, and work to create gaps in the evidentiary record. An attorney who helped design those tactics can anticipate and counter them earlier in the case. At The Law Office of Gregory M. McMahon, strategic preparation and genuine client focus go hand in hand. Injured workers and their families can expect candid advice, careful attention to the facts, and a focused effort to hold negligent entities accountable.
Understanding Brain Injuries & Their Long-Term Impact
Traumatic brain injuries range from concussions on the mild end through contusions, diffuse axonal injury (widespread tearing of the brain’s nerve fibers), and penetrating trauma on the severe end. Even a mild traumatic brain injury can disrupt concentration, cause persistent headaches, and alter how a person processes information, sometimes for months or longer. More serious injuries can affect memory, decision-making, mood regulation, and basic coordination, often requiring ongoing rehabilitation, therapy, and home support.
Not all brain injuries follow an obvious traumatic event. Certain chemicals can affect the central nervous system gradually through a process called neurotoxicity, and repeated low-level exposures can accumulate into serious harm. When symptoms develop over time, families may not immediately connect them to a workplace or industrial setting, which is why early medical evaluation matters even when the cause isn’t yet clear.
Beyond the direct medical effects, a brain injury can reshape a family’s financial situation significantly. A person who once worked in a demanding role may be unable to return to the same job or earn at the same level. In the Chicago area, where rehabilitation, assistive devices, and home support carry real costs, understanding how a claim may account for future care is an important part of any legal conversation. Illinois doesn’t cap non-economic damages such as pain and suffering in personal injury cases, which means the full human impact of a brain injury is part of what a claim can address.
How Serious Brain Injuries Happen in Chicago Workplaces & Communities
The brain injury cases handled by The Law Office of Gregory M. McMahon often share a common thread: they involve environments where corporate decisions about safety, maintenance, training, or chemical handling directly affect workers and nearby communities. In and around Chicago, that includes industrial facilities, rail yards, warehouses, and transportation corridors where heavy equipment and hazardous substances are part of daily operations.
In railroad and industrial settings, a momentary lapse in safety can have catastrophic injury outcomes. A fall from height, a blow to the head from unsecured cargo, or a collision involving rail or industrial vehicles can all result in serious brain trauma. In other situations, failure to follow proper procedures for storing or venting chemicals can expose workers to substances that affect the brain over time.
These incidents rarely happen in isolation. They may stem from patterns of understaffing, rushed schedules, inadequate protective equipment, or pressure to prioritize production over safe practices. Multiple entities can be involved, including large employers, contractors, and rail carriers. Identifying who made which decisions and how those decisions contributed to an injury is central to building a strong case. In and around Chicago, these events can occur across the Calumet industrial corridor and at busy rail facilities serving regional freight traffic, each with its own regulations, industry customs, and potential hazards.
What Compensation May Be Available in a Chicago Brain Injury Case
A serious brain injury typically generates both immediate and long-term losses. Understanding the categories of recoverable damages and the legal rules that shape them is an important step before resolving any claim.
Types of Recoverable Damages
Economic damages in a brain injury claim can include emergency treatment, surgery, medications, rehabilitation, and the projected cost of future medical needs. Lost wages and reduced earning capacity are also recoverable when an injured person can’t return to the same role or level of employment. Non-economic damages address pain and suffering, emotional distress, and loss of enjoyment of activities that were once central to daily life.
Illinois Comparative Negligence & Corporate Conduct
Illinois applies a modified comparative negligence rule under 735 ILCS 5/2-1116. A plaintiff can recover only if found 50% or less at fault, and any recovery is reduced proportionally by the plaintiff’s own share of fault. In cases involving corporate conduct, evidence of safety violations, deliberate understaffing, or ignored hazard reports can affect how a claim may be valued during negotiation or at trial. Corporate defendants routinely attempt to shift fault onto the injured worker, and building a record that accounts for and counters that effort is part of the investigation process from the outset.
Because Cook County Circuit Court and other local venues each have their own procedural rules and scheduling practices, how damages are documented and presented matters. Families benefit from speaking with counsel familiar with how these cases move through the courts serving the Chicago area.
How The Law Office of Gregory M. McMahon Builds Brain Injury Cases Against Corporations & Railroads
Brain injury claims involving corporate negligence or railroad incidents require careful investigation into both the medical picture and the corporate conduct that set the stage for harm. The Law Office of Gregory M. McMahon approaches these cases with a structured plan shaped by McMahon’s years inside major company defense teams.
Developing the Medical Picture
The firm begins by working to understand the full scope of the injury. That process typically includes reviewing hospital records, imaging studies, therapy notes, and information from treating providers, alongside listening carefully to the injured person and family members about changes in memory, behavior, or physical ability that may not appear on a scan but are very real in daily life.
Understanding long-term prognosis often requires input from neurologists, rehabilitation specialists, and therapists familiar with the person’s daily challenges. In serious matters, the relevant questions include whether the individual can return to the same kind of work, what support they will need at home, and how future care should factor into negotiations with a corporate defendant. Life care planning and projected future medical costs are often central to valuing these claims appropriately.
Examining Corporate Conduct
Alongside the medical review, the firm examines how and where the injury occurred. In a toxic exposure case, that can involve reviewing work history, exposure pathways, safety data sheets, and corporate chemical-use policies. In a railroad or industrial matter, it may include operating rules, maintenance records, training materials, and internal communications about safety concerns. Knowing where companies store key information and how they may characterize it is a product of years spent inside those defense structures.
Anticipating Defense Strategies
Drawing on prior defense work, McMahon prepares from the outset for causation disputes, preexisting condition arguments, and attempts to limit the evidence a jury sees. The firm works to connect medical evidence, exposure or trauma history, and corporate decision-making into a clear account of both fault and long-term impact. When defense teams raise procedural challenges or seek to narrow the case, The Law Office of Gregory M. McMahon is positioned to push back with a record built to withstand those efforts.
The Legal Process for Brain Injury Lawsuits in the Chicago Area
Most brain injury claims involving corporate negligence begin with an investigation phase during which medical records, workplace documents, and other evidence are gathered and reviewed. If the facts support moving forward, a lawsuit may be filed in Cook County Circuit Court or another local venue, depending on where the injury occurred and which companies are involved.
Filing Deadlines That Apply to These Claims
Illinois personal injury claims must generally be filed within two years under 735 ILCS 5/13-202. Railroad workers covered by the Federal Employers’ Liability Act (FELA) have a separate federal deadline of three years under 45 U.S.C. Section 56, distinct from the Illinois personal injury rule. For cases involving gradual toxic exposure, the discovery rule under Illinois law may delay the start of the limitations period when the connection between symptoms and workplace conditions wasn’t immediately apparent. Because that determination depends on the specific facts of each situation, early legal consultation can help ensure deadlines are properly identified. Settlement negotiations with an insurer don’t pause the clock. The statutory period continues to run regardless of ongoing discussions.
Discovery, Negotiation, & Trial
From filing, cases typically enter discovery, where both sides exchange records, take depositions, and work with medical and technical experts on the issues at the center of the case. Many brain injury cases resolve through negotiation or mediation; others proceed to trial. Throughout each stage, The Law Office of Gregory M. McMahon keeps clients informed about what is happening, what choices they face, and how each decision may affect timing and risk.
What to Do If You Suspect a Brain Injury After an Incident
Medical needs come first. If there is any concern about a head injury, seek emergency care or see a doctor as soon as possible, even if the person seems mostly alert. Some brain injuries aren’t obvious right away, and early evaluation protects both health and any future legal claim.
After immediate medical needs are addressed, families can take practical steps to protect their rights. Keeping a written record of symptoms, mood changes, and difficulties with memory or daily tasks during the first weeks and months can be valuable. Saving copies of medical records, discharge instructions, and therapy notes makes it easier to document how the injury has developed over time.
Where the injury may be connected to a workplace, rail yard, or industrial site, preserving information about the incident is equally important. That can include written reports, witness names, photographs, and notes about observed safety problems or prior incidents. Because companies often control much of the key evidence, contacting a brain injury attorney early can help ensure records are requested and preserved before they disappear or are reframed by the defense. Keeping appointment summaries, billing statements, and provider recommendations in one place also helps document both past treatment and anticipated future care.
Why Local Representation Matters for Brain Injury Claims in Chicago
Brain injury claims in the Chicago area may be governed by Illinois personal injury law, FELA for railroad workers, or both, and the applicable legal framework affects where a case is filed and which legal theories apply. A brain injury lawyer Chicago workers and families turn to for these cases should be familiar with both state and federal statutes, as well as the industrial and rail environments where so many of these injuries occur.
Cook County Circuit Court is the primary civil trial venue for injuries arising in Chicago, and familiarity with its scheduling practices and local procedures can help a case move more efficiently. Chicago and the surrounding region include major rail lines, the Calumet industrial corridor, and commercial freight hubs where workers face significant hazards from both acute incidents and ongoing exposure. The Law Office of Gregory M. McMahon focuses on representing people hurt in these environments, whether through a sudden traumatic event or through exposure that builds up over time. Local counsel who understands Chicago-area healthcare providers and rehabilitation centers can also help connect a client’s treatment records to long-term care needs, which strengthens the documentation of future damages.
Frequently Asked Questions
How Do I Know If My Loved One’s Head Injury Is Serious Enough for a Legal Case?
Whether a brain injury supports a legal claim depends on documented medical facts and evidence that another party created unsafe conditions or failed to act with reasonable care. Documentation of a concussion or more serious brain trauma, along with ongoing symptoms that interfere with work or daily life, helps establish the medical significance of the injury. During a free initial consultation, The Law Office of Gregory M. McMahon can review available records, discuss how the injury has affected your family, and assess whether further legal review is appropriate.
What If the Company Says My Brain Injury Was Caused by Something Else?
Companies and insurers frequently argue that a brain injury is unrelated to work, exposure, or an incident on their property. They may point to prior medical issues, age, or other events as alternative explanations. McMahon spent years on the defense side and knows these tactics well. When The Law Office of Gregory M. McMahon evaluates a claim, the firm looks at the full picture: timing of symptoms, medical imaging, work and exposure history, and the pattern of complaints before and after the incident. That analysis is used to challenge unfair attempts to shift blame away from negligent conduct.
Will I Have to Deal Directly With the Company or Its Insurance Lawyers?
Once the firm is formally retained, it takes over communications with the company, its insurers, and their attorneys. That arrangement lets injured people and families focus on medical care and daily life rather than fielding calls from adjusters or defense counsel. The Law Office of Gregory M. McMahon handles correspondence, negotiates with insurers, and responds to legal filings, while keeping clients informed about developments and decisions that require their input. When direct involvement is necessary, clients receive guidance about what to expect and how to prepare.
How Does a Former Corporate Defense Attorney Help Me in a Brain Injury Case?
A lawyer who has defended major corporations understands how those entities think about risk, set strategy, and value cases. McMahon uses that background to identify the kinds of documents, internal communications, and procedural issues that companies may prefer to keep from plaintiffs. He is familiar with how large organizations manage internal investigations, respond to safety complaints, and prepare their own witnesses. That insight allows The Law Office of Gregory M. McMahon to develop more targeted discovery requests, build case themes that address likely defense arguments before they are raised, and avoid being caught off guard by tactics he helped design.
How Long Do Brain Injury Cases Usually Take in the Chicago Area?
Timing varies based on the severity of the injury, how long medical stabilization takes, the number of corporate defendants, and whether the matter resolves through negotiation or proceeds to trial. Some claims may reach resolution within a year; others involving complex defendants or disputed medical issues can take longer. The Law Office of Gregory M. McMahon works to move cases forward responsibly and keeps clients informed about key milestones throughout the process.
What Does It Cost to Hire The Law Office of Gregory M. McMahon for a Brain Injury Claim?
The firm represents brain injury clients on a contingency fee basis. Legal fees are paid as a percentage of any recovery rather than up front. If there is no recovery, clients generally don’t owe an attorney’s fee. Specific terms are discussed and confirmed before representation begins. The firm also offers free initial consultations, so families can ask questions and understand the financial arrangement before making any decisions.
When Should I Contact a Lawyer After a Possible Brain Injury?
Contact a lawyer as soon as you suspect a brain injury may be connected to corporate negligence, railroad work, or toxic exposure. Early contact can allow the firm to identify and preserve important evidence, including incident reports, safety records, and exposure information, before it becomes harder to obtain. It also can help ensure that filing deadlines under Illinois personal injury law or FELA are clearly understood. A consultation doesn’t obligate you to move forward, but it can give you clarity about your options while the relevant facts are still fresh.
