“I started this firm after learning that the cancers that killed my father and grandparents were caused by asbestos, something we did not realize until it was too late to hold anyone accountable. That experience is why we built this site: so that no other family misses their chance to ask the questions, hear the options, and decide for themselves what to do.”
