02 · Who we represent
Start with the work you did.
Asbestos & mesothelioma
Mesothelioma, lung cancer, asbestosis and other asbestos-related illness, including exposure carried home on a family member's work clothes. We file lawsuits, bankruptcy trust claims and wrongful death claims.
Asbestos & mesothelioma claimsYou worked for a railroadRailroad workers (FELA)
Railroad workers are not covered by state workers' compensation. Your claim falls under the Federal Employers' Liability Act, and it has to prove the railroad's negligence. We handle injuries on the job and cancers tied to asbestos, diesel exhaust and benzene.
Railroad injury and cancer claimsYou worked in a mill, refinery or plantWorkers' compensation
Occupational cancer and lung disease from steel, refining, chemical and construction work in Illinois and Indiana. There are usually two claims here, not one.
Workers' compensation claimsNot sure which applies? Careers that mixed railroad and industrial work can carry more than one claim. Ask us.
03 · The other side
He is not guessing about the other side's strategy. He implemented it daily.
Gregory M. McMahon began his career defending some of the world's largest Fortune 500 companies against people who developed cancer from toxic exposure. He did that for more than two decades, on thousands of cases. For the last four years he has represented only the people on the other side of those cases.
What a corporate defense does, and he knows from the inside
Delay or deny
The tactics and maneuvers corporate defendants use to delay a claim or deny it.
Attack the evidence
The kinds of evidence, and the weak points, that a defense team goes after.
Shrink the number
The strategies used to minimize the value of what a person has suffered.
We use that knowledge to anticipate those moves and to put you in the strongest position we can for negotiation or trial.

Do not negotiate with the railroad's claims agents alone. They work to minimize your payout.

06 · Your attorney
Gregory M. McMahon, founder.
Gregory started out defending Fortune 500 companies in complex lawsuits brought by people who developed cancer after exposure to toxic substances. Over more than two decades he became closely familiar with how large corporations approach high-stakes litigation.
Then he changed sides. Today he represents the people those companies harmed. This is a smaller, focused practice, and clients work directly with him.
