A trusted advisor for our company's complex securities matter

Our company engaged Bill Paine at WilmerHale in Boston to navigate a complex SEC inquiry related to a recent public offering. With nearly four decades of experience, his deep knowledge of securities regulation was immediately apparent. He provided a clear, strategic roadmap that balanced regulatory compliance with our business objectives. His recognition as Lawyer of the Year in this field was well-earned; his analysis was precise, and his counsel instilled confidence in our board during a stressful period. The matter was resolved favorably, largely due to his steady guidance and his firm's formidable resources. While the outcome was excellent, the billing structure for a matter of this scope was substantial, as expected with a top-tier firm, and there were occasional delays in receiving draft documents from junior associates, though Bill himself was always accessible for critical discussions. For high-stakes securities or commercial litigation matters in Boston, his expertise is invaluable.
