Kristen A. Johnson is a partner in Hagens Berman Sobol Shapiro LLP’s Boston office, where she has worked since 2007.  She focuses on combatting fraud and anticompetitive conduct within the pharmaceutical industry.    

Ms. Johnson's recent successes include a $150 million settlement on behalf of direct purchasers in In re Flonase Antitrust litigation.  Ms. Johnson conducted the direct examination of former FDA commissioner Dr. David Kessler during an evidentiary hearing and briefed the opposition and argued against the defendant’s motion to exclude Dr. Kessler.  The case settled less than a week after the Court issued an order permitting Dr. Kessler to testify in full.  Ms. Parker was also instrumental in the recent Wellbutrin XL ($37.5 million partial settlement) and Wellbutrin SR ($21.5 million) antitrust settlements. 

Ms. Johnson is currently alternate lead counsel in the In re New England Compounding Pharmacy Litigation Multidistrict Litigation (MDL 2419).  During the nascent stages of the MDL, Ms. Johnson was personally appointed liaison counsel to speak for the at least 751 victims who contracted fungal meningitis or suffered other serious health problems as a result of receiving contaminated products produced by NECC. 

In 2011, Public Justice nominated Ms. Johnson and the rest of her trial team for Trial Lawyer of the Year for their work securing a $142 million RICO verdict against Pfizer for fraudulently marketing the drug Neurontin.  Ms. Parker also oversaw the implementation of the $80 million Vioxx settlement on behalf of litigating third party payers. 

Ms. Johnson is actively involved in In re Nexium Antitrust Litigation (MDL No. 2409); In re Lipitor Antitrust Litigation (MDL No. 2332), In re Effexor XR Antitrust Litigation, (District of New Jersey, No. 11-cv-5479); and In re Prograf Antitrust Litigation (MDL No. 2242).

Ms. Johnson graduated cum laude from Dartmouth College and earned her J.D. at Boston College Law School.  Ms. Johnson coached the B.C. Law Phillip C. Jessup International Law Moot Court Team for several years following graduation.

Ms. Johnson is admitted to practice in the Commonwealth of Massachusetts, the District of Massachusetts, and the First Circuit Court of Appeals.  She is a member of the American Association for Justice and Public Justice’s Class Action Preservation Project Committee.

Awards/ Recognition

In 2011, Public Justice nominated Ms. Johnson and the rest of the Neurontin trial team for Trial Lawyer of the Year for their work in securing a $142 million verdict against Pfizer for suppressing and manipulating the results of scientific studies that showed Neurontin did not work to treat the off-label indications Pfizer was heavily promoting.
