Boston, MA – International law firm Sullivan & Worcester has elevated six attorneys to partner in its Boston and New York offices, effective January 1, 2026. The promotions follow a period of sustained growth across key practices and markets and reflect the firm’s continued investment in developing talent from within. The firm has elevated these attorneys, all of whom were promoted from the associate ranks, in recognition of their exceptional leadership, client service and business development achievements. The newly promoted partners include Boston-based attorneys Ryan M. Rosenblatt (litigation) and Ryan C. Tompkins (private clients/trusts & estates), as well as New York attorneys Ilana Neck Levin (capital markets), Anna Lea McNerney (litigation), Brendan O’Brien (capital markets) and Christopher K. Shields (litigation). “Each of these attorneys has demonstrated outstanding leadership and a consistent ability to deliver results for clients,” said Managing Partner David Nagle. “They have successfully handled complex, high-stakes matters while growing their practices in ways that strengthen the firm as a whole. We are proud to welcome them to the partnership and confident they will continue to make meaningful contributions through top-level service and creative, practical solutions.” The partner promotions come at a time of sustained momentum for the firm following the implementation of a targeted strategic plan in 2024. That momentum has been driven by strong demand across key practice areas, including REITs, Capital Markets, Corporate, Investment Management and Tax. “Our capital markets teams in New York, Boston and Tel Aviv have achieved remarkable success this year by delivering thoughtful, responsive counsel on some of the market’s most complex and innovative transactions,” said David Danovitch, Managing Partner of the New York Office and head of the firm’s U.S. Capital Markets and Regulatory and Compliance Practices. “The growth we’ve seen in our New York office, in particular, reflects both the strength of our people, the firm’s strategic plan to grow in New York and the trust our clients place in us. We’re energized by what we’ve accomplished and excited about the opportunities ahead as we continue to build our practice and deepen our footprint in New York and beyond.” Supporting this momentum, Sullivan added 22 attorneys in 2025, many of whom joined from larger law firms or organizations, attracted by the firm’s collaborative culture, strong growth trajectory and expanding platform. The firm also continued its strategic expansion in life sciences and intellectual property, building on the addition of Thomas Meyers and Zachary Hyde and formally launching a Life Sciences and Patent Practice Group at the end of 2024. This growth further strengthened the firm’s ability to serve innovative and emerging companies in Boston and across the globe. The firm’s London office also enhanced its market-leading Trade Finance practice with the acquisition of Robert Parson from Squire, Patton, Boggs and Matthew Cox from Holman Fenwick Willan. The Washington, DC office also added new partners: Stephanie Monaco joined the firm's prestigious Investment Management group from Mayer Brown, and Cameron Cosby joined the firm’s premier REITs practice from Fried Frank. “At Sullivan, we’re committed to providing lateral partners from larger firms with more than just a new platform – we offer genuine support, individualized attention, and the resources they need to grow their practices with confidence,” said Nagle. “We’ve built a culture where attorneys feel valued and truly cared for, and we’re proud to be a place where people can thrive both professionally and personally.” The firm continues to build on its expanded platform and to invest in practices that have strengthened Sullivan’s reputation among clients ranging from emerging businesses to established Fortune 500 companies. In addition to the firm’s London office abroad, its Tel Aviv presence has furthered enhanced the firm’s work in the life sciences and biotech sector, with Sullivan representing a significant share of Israeli companies listed on Nasdaq. The firm has also strategically focused on expanding its presence in Ireland, Finland and across Asia. “While many large firms are merging to create massive conglomerates, we have remained focused on what truly differentiates us and the value we deliver to our clients,” said Danovitch. “We’ve invested strategically in technology to enhance efficiency and, just as importantly, in our people. Our clients value knowing that the lawyers they hire are the ones deeply engaged in their matters and fully committed to achieving the best possible results. That focus has been central to our success.” Additional information about each newly promoted partner and their practice areas is provided below.
