Mark Didak, Of Counsel, practices a wide variety of state and federal civil cases at the trial and appellate court levels, and primarily focuses on insurance coverage and bad faith matters, consumer class actions, and legal malpractice litigation on behalf of both plaintiffs and defendants. During his nearly three decades of practice, Mr. Didak has obtained millions of dollars in settlements on behalf of individual and business policyholders, and represented insurers as coverage or defense counsel on more than one billion dollars worth of claims, including very large exposure claims of $800 million, $400 million and $220 million. He has earned an "AV" rating from Martindale-Hubbell, its highest rating for legal excellence and ethics, and he was selected as a Southern California "Super Lawyer" in insurance law in 2007, 2008, 2009, 2010, and 2011. He was also selected as a Southern California "Super Lawyer" in class actions and mass torts for 2012.

In his first class action, Mr. Didak was co-lead counsel in an action against a major health insurer which settled in favor of a class of over 3.5 million Californians–one of the largest classes in state history. He was also lead class counsel on behalf of hundreds of Quiznos franchisees who had paid franchise fees but were unable to open restaurants. That case settled favorably in 2010.

Among the many appeals he has handled are Malek v. Blue Cross (2004) 121 Cal.App.4th 44, which effectively invalidated Blue Cross's arbitration agreements in virtually all earlier versions of its California health plans, and Slaney v. Ranger Insurance Company (2004) 115 Cal.App.4th 306, which contributed significantly to the law concerning anti-SLAPP motions in malicious prosecution actions.

Before joining Arias Ozzello and Gignac, Mr. Didak was Of Counsel to one of Southern California's leading insurance defense firms. He has also continuously operated his own firm, the Law Office of Mark F. Didak, since 1990. From 1985 through 1988, he was associate general counsel, and later general counsel, to Escrow Agents' Fidelity Corporation, a legislatively-created fidelity insurer, and substantially drafted major revisions to California's Financial Code governing EAFC's operations that went into effect in 1988.

Born and raised in Los Angeles, Mr. Didak received his BA in anthropology from Reed College and his Juris Doctor from the University of Southern California.
