Bernstein Litowitz Berger & Grossmann Expands Corporate Governance Team with New Leadership and Addition of Noted Delaware Lawyer Anthony Calvano

January 8, 2026

NEW YORK and WILMINGTON, Del. (January 8) – Bernstein Litowitz Berger & Grossmann LLP, a top-ranked international investor law firm, announced the expansion and reorganization of its Department of Governance, including new leadership and the addition of Anthony Calvano as a partner and Tayler Bolton, joining later this month, as an associate in the firm’s Delaware office, further strengthening BLB&G’s preeminent corporate governance practice.

The co-heads of the department are Partner Greg Varallo, head of BLB&G’s Delaware office for the past six-plus years, and Special Governance Counsel Mark Lebovitch, based in New York and Delaware. Varallo and Lebovitch, who recently rejoined BLB&G after retiring from the firm in 2023, each bring decades of experience litigating complex fiduciary duty and corporate governance cases in the Delaware Court of Chancery and courts across the country.

Anthony Calvano is an experienced corporate governance litigator with deep familiarity litigating complex fiduciary duty, merger-related, and stockholder rights disputes in the Delaware Court of Chancery. Calvano joins BLB&G from Ross Aronstam & Moritz, where he focused on complex commercial litigation, including representing stockholders in high-stakes corporate governance litigation, and he previously practiced at elite corporate defense firm Richards, Layton & Finger. Calvano also served as a judicial law clerk to the Honorable Vice Chancellor J. Travis Laster of the Delaware Court of Chancery. He brings significant courtroom experience, including multiple trials, and Delaware-focused expertise that further bolsters the firm’s trial bench. 

“Anthony’s arrival is a major addition to our governance platform,” said Varallo. “He is a highly respected Delaware trial lawyer with exceptional judgment and deep experience litigating exactly the kinds of governance and investor-driven cases that define our practice. His presence further strengthens our ability to represent stockholders in the most demanding and consequential governance disputes. And Tayler’s deep experience as an investor lawyer will be a welcome addition to the quickly growing team.”

“Under the leadership of Greg and Mark—and with the addition of Anthony Calvano and Tayler Bolton—we are excited about the next chapter of our Corporate Governance group,” said Hannah Ross, BLB&G partner and member of the firm’s Executive Committee. “This team reflects the depth, experience, and trial readiness that define BLB&G, and we are confident it will continue to deliver outstanding results for shareholders.”

Together, Varallo and Lebovitch will lead a fully staffed and deeply experienced team of attorneys—including Calvano and other seasoned partners—who have successfully prosecuted landmark corporate governance cases in Delaware and courts across the United States.

Greg Varallo is widely regarded as one of Delaware’s preeminent trial lawyers and has served as lead counsel in many of the firm’s most significant corporate governance victories. Varallo led the BLB&G trial team that secured a landmark decision in the Delaware Court of Chancery rescinding Elon Musk’s historic $56 billion Tesla compensation plan, finding that Tesla’s board of directors breached its fiduciary duty in granting the pay package. He recently argued the appeal before the Delaware Supreme Court, which affirmed the trial court’s liability findings while modifying the damage award. He was also a member of the BLB&G team that achieved a $67 million post-trial win in the stockholder class action related to Vista Equity Partners’ acquisition of Mindbody. Varallo is a Fellow of the American College of Governance Counsel and a Fellow of the American College of Trial Lawyers – an invitation-only Fellowship of exceptional trial lawyers from the United States and Canada who have demonstrated the very highest standards of trial advocacy, ethical conduct, integrity, professionalism, and collegiality.

Mark Lebovitch, who founded BLB&G’s Department of Governance in 2006 and opened the firm’s Delaware office in 2019, is a renowned shareholder advocate who played a central role in many significant corporate governance developments over the past 25 years. During his prior tenure at BLB&G, Lebovitch carefully selected each of the firm’s corporate governance cases, many of which presented novel theories that advanced the law to better protect stockholders, and negotiated virtually all settlements in corporate governance matters, helping to establish BLB&G as a trailblazer in stockholder litigation and governance reform.

Lebovitch recently rejoined the firm after retiring in 2023 to teach courses on “Legal Financial Arbitrage” at Columbia Law School and “Advanced Topics in Corporate Law” at the University of Pennsylvania Carey School of Law. He is also a Fellow of the American College of Governance Counsel.

“Jumping right back into litigation after spending two years in the classroom has been invigorating,” said Lebovitch. “Thinking about Delaware law through an academic lens has given me fresh perspectives that will help us offer clients the best advice, execute winning litigation strategies, and develop new cases that will restore the right balance in stockholder rights. BLB&G’s governance platform is as strong as ever, and I look forward to representing investor clients in corporate governance cases for years to come.”

In addition to Calvano, BLB&G’s newly reorganized Department of Governance includes seasoned partners with extensive trial, investigative and advisory success in corporate governance litigation:

• Rebecca Boon, a nationally recognized corporate governance and securities litigator with nearly two decades of experience, was a leader of the BLB&G team that secured a $90 million recovery and the creation of a first-of-its kind board-level oversight body for harassment and misconduct through the landmark derivative litigation against 21st Century Fox arising from systemic sexual and workplace harassment at Fox News. Boon also prosecuted the stockholder derivative action against Guess, Inc., arising from allegations of sexual misconduct by the company’s co-founder, obtaining a $30 million recovery and significant corporate governance reforms. Boon currently leads the shareholder derivative action against eXp World Holdings alleging board-level oversight failures related to workplace misconduct.
• Anya Freedman advises institutional investors on fiduciary law and corporate governance matters, providing education and counsel to help BLB&G’s clients make informed decisions regarding stockholder investigations and litigation strategy. Freedman draws upon nearly a decade of experience as the principal legal advisor to the City of Los Angeles pension systems, where she advised boards overseeing approximately $70 billion in trust funds on governance, fiduciary oversight, investment policy, regulatory compliance and participation in corporate governance litigation. She is a member of the Council of Institutional Investors’ Markets Advisory Council and regularly speaks to pension and institutional investor audiences on fiduciary law, corporate governance and shareholder rights.
• Robert “Rocky” Kravetz, a former Assistant U.S. Attorney and Chief of Appeals for the District of Delaware, brings nearly 20 years of experience leading complex investigations and trials involving financial institutions, securities fraud and corporate misconduct. His background includes coordinating large-scale investigations with securities and banking regulators and trying multiple cases to verdict as lead counsel. Kravetz serves as BLB&G lead trial counsel, alongside Varallo, in the stockholder class action in Oklahoma state court challenging founder Harold Hamm’s 2022 take-private transaction of Continental Resources, scheduled for a jury trial in mid-2026.
• Jeremy Robinson is a nationally recognized litigator who has dedicated his career to fighting corporate misconduct. He recently led the prosecution of a groundbreaking derivative action in New York state court against Credit Suisse’s former directors and officers. This action alleged claims under Swiss corporate law arising from defendants’ alleged failure to oversee risk management systems at the Swiss bank, which led to the bank suffering significant losses following the collapse of hedge fund counterparties, including Archegos Capital. Pending court approval, the team achieved a record $115 million settlement, the largest recovery for derivative oversight claims in New York state court history. Robinson also helped secure a recovery of more than $250 million, just weeks before trial, in Allergan Williams Act Litigation, which arose from alleged insider trading violations in the hostile tender offer context. He also helped secure a $122.5 million recovery in the stockholder class action challenging the stock-for-stock merger of Viacom and CBS.

The department’s work is further strengthened by a deep bench of experienced associates who add significant litigation capacity and Delaware-focused expertise. BLB&G Senior Associates Mathews de Carvalho and Jonathan D’Errico are expanding their roles to practice in both the firm’s Securities Fraud Litigation group and its Department of Governance. Before joining BLB&G, De Carvalho and D’Errico both practiced at Weil, Gotshal & Manges, where they gained substantial experience litigating complex corporate governance matters on the defense side.

In addition, as noted, Tayler Bolton is joining the firm’s Delaware office as an associate. Bolton previously practiced at Robbins Geller Rudman & Dowd, where she prosecuted breach of fiduciary duty actions on behalf of investors, with a focus on matters before the Delaware Court of Chancery. Bolton previously served as a law clerk to the Honorable Diane Clarke-Streett of the Superior Court of the State of Delaware and is an active leader in the Delaware bar, serving on the Delaware State Bar Association Executive Committee and as co-chair of its Young Lawyers Section. Together, these attorneys further deepen the department’s associate bench and enhance the firm’s ability to litigate sophisticated corporate governance cases through trial.

The Department of Governance is further supported by its longstanding members, each of whom bring deep institutional knowledge and litigation experience.

• Mae Oberste, a senior counsel and long-time practitioner, has served on the Delaware State Bar Association’s Executive Committee since 2020. She plays a central role in the documentation, negotiation and presentation of complex Delaware settlements. Before joining the firm, Oberste clerked at the Delaware Court of Chancery for then-Vice Chancellor Tamika R. Montgomery-Reeves.
• Shiva Mohan, an associate, specializes in new case development and works closely with Mark Lebovitch to identify and evaluate emerging corporate governance matters, leveraging deep experience in governance theory, fiduciary duties and market-wide misconduct trends to develop high-impact case theories for the benefit of the firm’s clients.
• John Mills, a senior counsel, focuses on negotiating, documenting and obtaining court approval of the firm’s securities, merger and derivative settlements. He has been at the firm for nearly two decades and has finalized some of the most significant settlements in Delaware history, including Freeport-McMoRan ($154 million) and News Corp. ($139 million plus corporate governance enhancements).
• Ronald Wittman is an experienced case manager with extensive knowledge of practice and procedure in the Delaware Court of Chancery and Delaware Supreme Court. He plays a critical role in managing complex governance litigation through trial, appeal and settlement.

The Department of Governance also includes senior governance professionals based in Europe who support the firm’s European institutional investor clients on governance issues and shareholder litigation: 

• Anatoli van der Krans, BLB&G’s Managing Director of European Investor Relations, is one of Europe’s leading experts on corporate governance and shareholder litigation. Van der Krans advises European asset managers and pension funds on developing and implementing shareholder litigation policies and on their participation in U.S. and global securities and governance actions. Based in Amsterdam, he works closely with clients to provide practical guidance tailored to the European regulatory environment and has been involved in numerous high-profile securities class and private actions, including serving as the institutional investor representative in litigation across the United States, Europe and Asia.
• Hans Ek, BLB&G’s Senior Advisor for European Investor Relations, is a recognized authority on corporate governance, responsible investment and securities litigation. Based in Stockholm, Ek previously served for more than two decades as a senior executive at SEB Investment Management and works closely with European clients to integrate shareholder litigation into responsible investment and active ownership strategies, drawing on deep experience in asset management, ESG implementation and governance reform.

The group is further reinforced by a senior staff attorney team, including David Carlet, Stavros Katsetos, Maureen McCarren and Rebecca Reyhani, each of whom has been with the firm for more than eight years. These attorneys have been central to the evidentiary development of the department’s historic cases and bring added continuity, judgment and deep familiarity with Delaware corporate litigation practice.

Additionally, the department draws on the expertise of BLB&G’s preeminent Case Development and Client Advisory Group, comprised of experienced and specialized attorneys, financial and research analysts, data engineers, and information technology professionals who work with the firm’s clients to identify and develop meritorious corporate governance cases. The department is further supported by electronic discovery experts and settlement administrators who provide critical support throughout the course of litigation.

“It is wonderful to welcome Anthony to the firm and to have Mark back litigating shoulder to shoulder with me,” said Varallo. “We have an extraordinary group of partners, attorneys and legal professionals, and we are fully equipped to continue bringing the most sophisticated and impactful governance cases for our clients.”
