Our company faced a high-stakes, cross-border merger that involved intricate securities regulations and significant shareholder considerations. We were referred to Mark Wishner at Greenberg Traurig, and it was the best decision we could have made. Mark’s 53 years of experience, particularly his deep background in securities offerings and corporate transactions, was immediately evident. He didn't just review documents; he provided a strategic roadmap, anticipating regulatory hurdles and structuring the deal to protect our interests while ensuring a smooth closing. His recognition in Corporate Law and Securities/Capital Markets is well-deserved. Mark’s calm, seasoned guidance through the complexities of SEC filings and international due diligence was invaluable. He is the epitome of a trusted advisor—exceptionally sharp, thoroughly professional, and genuinely invested in achieving the optimal outcome. The transaction concluded successfully, and we have immense confidence in his counsel for any future corporate matters.
