Expert guidance through a complex M&A transaction

Dan O'Neil provided exceptional counsel during our company's recent acquisition. His deep knowledge of corporate governance and M&A law was evident from our first meeting. He navigated complex compliance issues with precision and foresight, ensuring a smooth process. Dan’s recognition in Mergers and Acquisitions Law is well-deserved. He was always accessible, explaining intricate details in clear terms. The transaction closed successfully, largely due to his meticulous preparation and strategic advice. I highly recommend Dan for any corporate legal matter requiring both expertise and a practical approach.
