Depth and Judgment, Delivered with Focus
Lumen Law Group was founded to deliver senior-level counsel and a thoughtful, results-driven approach to clients who value clear thinking and guidance that holds up under scrutiny. We bring the standards of elite firms—without the layers—advising on transactions, governance, and strategy with experience trusted by business leaders, founders, and investors.
Sophisticated, Senior-Led Counsel
Every engagement is led by Mark Haddad, drawing on decades of experience advising companies, founders, and investors on high-stakes matters. This direct involvement means clients benefit from steady judgment and a perspective shaped by working with leading institutions and entrepreneurial businesses alike.
Integrated Legal, Financial, and Operational Insight
Mark’s background includes roles at Sullivan & Cromwell, Goldman Sachs, Jones Day, and PwC, as well as serving as General Counsel to a global investment manager. This combination of legal, financial, and operational experience allows clients to make decisions with a full understanding of risk, opportunity, and execution challenges.
Trusted Resources When Needed
When matters require specialized knowledge or additional capacity, Mark draws on a network of senior lawyers and advisors developed over decades in practice. This selective approach allows clients to access tax, employment, intellectual property, regulatory, and transactional specialists as needed—while maintaining a single point of accountability.
A Trusted Partnership
Clients often engage Mark as a steady advisor whose role extends beyond transactions. They value his ability to balance judgment and pragmatism, anticipate issues early, and ensure work is executed with consistency and care over time. Many describe him as a lawyer’s lawyer—someone relied upon for thoughtful guidance in complex situations.
