A formidable advocate in complex commercial litigation

When our company faced a high-stakes antitrust dispute with a former partner, we needed counsel with deep expertise and unflappable composure. John Bartko was exactly that. His decades of experience, honed since his Berkeley Law days, were immediately evident. He didn't just grasp the intricate commercial details; he anticipated opposing counsel's moves and built a defense strategy that was both aggressive and meticulously prepared. His recognition in white-collar defense and antitrust law is clearly well-deserved. Throughout the process, John was a steadying force—professional, accessible, and transparent. He secured a settlement that not only protected our interests but also preserved critical business relationships. I cannot recommend John and his firm highly enough for anyone navigating serious commercial or regulatory challenges.
