Ortoli Rosenstadt LLP is proud to celebrate its 20th anniversary, marking two decades of advising U.S. and international clients across a broad range of corporate, transactional and litigation matters. Proudly founded in the capital and business center of the world, New York City, the firm has grown from its original New York office to a global footprint spanning Miami, Singapore and Hong Kong through its Ortoli Rosenstadt Ye affiliate.As part of this milestone, Ortoli Rosenstadt is also announcing its move to a newly renovated space on the 9th floor of 366 Madison Avenue, maintaining the same iconic address while expanding its capacity to support clients and team growth.
“Reaching twenty years is both humbling and energizing”, said Co-Founding Partner Richard Ortoli. “From the beginning, our approach has been to offer clients the depth and sophistication of a large firm with the accessibility and speed of a boutique practice, and we continue to focus on building the next chapter with the same commitment to practical, high-quality counsel. We strive to invest in talent, infrastructure and client experience. This anniversary is a testament to our team and the clients who have trusted us along the way”.
“Building a firm that spans three countries and four cities was never the plan on day one; it happened because our clients needed us in those markets”, said Co-Founding Partner and Managing Partner William Rosenstadt. “That is what I am most proud of: every step of our growth has been driven by the relationships we have built. Our team’s entrepreneurial mindset and willingness to tackle any challenge are what set this firm apart”.
Over the past two decades, Ortoli Rosenstadt has guided hundreds of public and private companies through capital markets offerings, navigated complex cross-border M&A transactions, advised high-net-worth individuals and families on international estate planning and administration, and built long-standing relationships with clients across the U.S., Europe and Asia. The firm fosters a collaborative and innovative environment where attorneys with an entrepreneurial spirit work closely together across practice areas and offices to deliver creative, business-minded solutions. That culture has been central to the firm’s expansion and its dedication to supporting clients wherever they operate.
Ortoli Rosenstadt LLP’s new office address is: 366 Madison Avenue, 9th Floor, New York, NY 10017. The firm’s telephone numbers and email addresses are unchanged.
