Sly Onyia focuses his practice on defending automotive manufacturers in product liability litigation. His cases regularly involve a wide range of complex claims including catastrophic injury and wrongful death across the country.

Sly routinely prepares fact witnesses for deposition, conducts early case evaluations, prepares briefs and motions as well as drafts settlement proposals. He also drafts affidavits and notices of default for commercial litigation matters. Sly is an integral player in client meetings by providing administrative support and meeting preparation.
