Most recently, Alan served as Head of Global Tax for Viatris, Inc., formerly Mylan Inc., where he led the company’s worldwide tax organization from 2009 through April 2024 before transitioning into an advisory consulting role. In this capacity, he oversaw every aspect of the global tax function for a pharmaceutical company generating more than $15 billion in annual revenue. Working closely with the Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer, Treasurer, General Counsel, business unit leaders, and the Board of Directors, Alan became an integral strategic partner in shaping the organization’s financial and operational direction. His responsibilities extended far beyond compliance, encompassing corporate strategy, acquisitions, restructurings, international tax planning, financial reporting, and enterprise-wide decision-making.
Among Alan’s most significant accomplishments at Viatris was reducing the company’s worldwide effective tax rate from approximately 30 percent to 16 percent despite maintaining substantial research, development, and manufacturing operations across the United States and India. He directed tax planning for major acquisitions, dispositions, inversions, legal entity integrations, intercompany financing programs, and international restructurings while managing complex tax controversies in the United States, Australia, France, Germany, India, Italy, and the United Kingdom.

Even following his retirement from the executive role, Alan continues to advise Viatris on significant international tax matters and strategic planning initiatives as a consultant.
Prior to joining Mylan, Alan served as International Tax Counsel for GE Money, where he developed sophisticated strategies involving foreign tax credits, cross-border funding structures, joint ventures, and international business dispositions. His innovative planning enabled the organization to maximize tax efficiency while supporting global business expansion and strategic investments. Earlier, as Vice President of Tax at Chemtura Corporation, Alan successfully reduced the company’s worldwide effective tax rate from 36 percent to 32 percent within his first ten months while implementing technology modernization initiatives, reorganizing the tax function, improving reporting processes, and strengthening governance across a complex multinational organization.
One of the defining chapters of Alan’s career was his remarkable sixteen-year tenure with Pfizer, where he progressed through multiple leadership positions culminating in Senior Tax Counsel overseeing global tax planning and transfer pricing. During this period, he played a pivotal role in integrating the tax structures associated with Pfizer’s acquisitions of Warner-Lambert and Pharmacia, helping unify operations across dozens of international jurisdictions while identifying significant tax savings opportunities. His work included global transfer pricing strategies, foreign tax credit optimization, treasury planning, product sourcing strategies, business reorganizations, strategic alliances, mergers and acquisitions, and worldwide funding initiatives. Leading teams of tax professionals while collaborating closely with finance, treasury, accounting, legal, and operational executives, Alan consistently demonstrated an uncommon ability to bridge technical expertise with practical business leadership.
Alan began his distinguished professional career practicing tax law with the internationally respected law firms Debevoise & Plimpton and Schulte Roth & Zabel, where he advised clients on sophisticated domestic and international corporate transactions, acquisitions, reorganizations, partnership structures, debt restructurings, and cross-border investments. This legal foundation established the technical expertise that would become the cornerstone of his executive career while also shaping his disciplined, analytical approach to solving highly complex business challenges. His educational accomplishments are equally impressive, earning both a Juris Doctor and a Master of Laws in Taxation from New York University School of Law, where he served on the prestigious Law Review editorial staff and received the American Jurisprudence Award in Contracts. He also graduated summa cum laude from the State University of New York at Albany with a Bachelor of Arts in Political Science while earning Phi Beta Kappa honors.
Throughout his career, Alan has earned the trust of executive leadership teams because of his ability to understand not only financial issues but also the broader business implications behind every strategic decision.
