A formidable advocate with decades of high-stakes experience

Our company retained Harry Chamberlain to handle a complex insurance coverage dispute that had escalated to the appellate level. From the outset, his deep knowledge of both insurance law and appellate procedure was evident. He drew upon his 45 years of experience, including his work for Fortune 500 clients, to craft a strategy that was both sophisticated and pragmatic. His recognition in appellate practice is well-deserved; his briefs were exceptionally clear and persuasive, and his oral argument was masterful. We were very pleased with the outcome he secured. While his expertise is top-tier, the billing structure at a firm of Buchalter's caliber is significant, and there were occasional delays in receiving routine status updates from his team, which required a gentle nudge. That said, for high-value, complex litigation where the stakes are immense, Harry is an outstanding choice. His steady hand and institutional knowledge are invaluable assets.
