John H. Gionis
Civil & Criminal
This attorney’s practice branches into personal and catastrophic injury, medical malpractice, real estate, commercial litigation and trusts and estates. But it’s in the criminal law arena where he truly excels. White-collar crime cases involving fraud are a specialty, and Gionis is a formidable litigator on both the state and federal level. Both within his firm of Certilman Balin and among his peers, Gionis is known for his aggressive courtroom manner—his cross-examination style is the bane of those who oppose him in court. But he’s always been an overachiever. Even in school, when he was working on his Juris Doctor at California Western School of Law at San Diego, he graduated in the top 2 percent of his class and received the Jurisprudence Award in Trial Advocacy.
