Prior to joining Buchanan, Jason spent 11 years with a large, global law firm during which he represented several clients in high-stakes, ‘bet the company’ matters. Jason was counsel to BP in government investigations and litigation related to the 2010 Deepwater Horizon disaster and to Volkswagen Group of America in government investigations related to the company’s alleged use of software to defeat government emissions tests.

Jason has deep experience with issues facing the healthcare and pharmaceutical industries. For the last eight years, Jason has served as national counsel for a number of generic pharmaceutical companies in litigation related to the publication and use of Average Wholesale Prices (“AWPs”) and other drug pricing metrics. Jason currently represents a generic pharmaceutical company in multi-district litigation alleging a conspiracy to fix generic drug prices.

What Clients Can Expect

Jason excels at devising creative, cost-effective strategies to help clients meet their legal and business objectives. He is most at home on his feet in court, arguing before a judge or jury. Clients commend Jason’s ability to quickly absorb complex and developing facts, and his common sense approach to even the thorniest legal problems.

For several years before law school, Jason was an account executive with a global public relations firm. This experience continues to inform Jason’s approach, which focuses not only on whether a course of action is legally sound, but how it will play with the judge, jury and others.
