Alexandra Walsh


Alexandra Walsh is a founding member of Wilkinson Walsh. She is an accomplished trial and appellate lawyer who has successfully led the representation of a range of clients in federal and state courts throughout the country.

Building on her extensive trial experience, in the last 6 months, Alexandra has led two trial teams to victory in critical litigations for the firm's longstanding client, Bayer Corporation. The first case challenged the warnings that accompany Bayer Corporation’s market-leading blood thinner medication, Xarelto. The second, a multi-state class action, alleged that Bayer Corporation used deceptive claims to market its multivitamin One A Day. In both cases, the jury returned complete defense verdicts after less than two hours of deliberation. Alexandra has been tapped to try the first case in a national litigation challenging Essure, a permanent birth control method previously marketed by Bayer Corporation. That trial is scheduled to commence in November of this year.

Before founding Wilkinson Walsh, Alexandra was a partner at Paul, Weiss, Rifkind, Wharton & Garrison in Washington, D.C. She attended Bowdoin College and Stanford Law School. Prior to beginning her legal practice, Alexandra clerked for Chief Judge Merrick Garland of the D.C. Circuit and Supreme Court Justice Stephen G. Breyer.
