Attorney Jo Anna Pollock is a shareholder at Simmons Hanly Conroy in the Complex Litigation Department, where she focuses on public nuisance, class actions, sex abuse and environmental litigation. She devotes her practice to representing people, county governments and businesses that have been harmed through the wrongdoing of others.

Jo Anna works on cases nationwide through all stages of the litigation process. She has spent the last 20 years in trial and appellate courts across the country securing more than a billion dollars on behalf of her clients.

“Every day, I wake up determined to give a voice to people who would not otherwise have one,” Jo Anna said. “No case is too difficult, and no defendant too big for us.  We will go anywhere to find the justice that our clients deserve.”

Fighting the Opioid Epidemic

Currently, Jo Anna represents the interests of governmental bodies across the country in the national opioid litigation MDL pending in the Northern District of Ohio (MDL 2804) and in the coordinated New York state court litigation, Index No. 400000/2017 In re: Opioid Litigation, Supreme Court of the State of New York, County of Suffolk.

Leading up to the New York trial’s opening arguments, several original defendants, including Johnson & Johnson and the pharmacies CVS, Walgreens, Rite-Aid and Wal-Mart, were severed from the trial. After a seven-month trial, the team recovered more than $1.7 billion in settlements against opioid manufacturers and distributors.

Key results included:

  • The three largest U.S. drug distributors — McKesson Corporation, Cardinal Health Inc. and AmerisourceBergen Drug Corporation — settled claims with New York State for a combined $1.18 billion.
  • Endo Pharmaceuticals and its subsidiaries agreed to a settlement with New York State, and Suffolk and Nassau Counties, totaling $50 million.
  • Johnson & Johnson settled with the state of New York for $263 million, and as part of their agreement, the company agreed to stop making opioids.
  • Former opioid manufacturer Allergan settled on the eve before closing arguments for $200 million.

These settlements provided recoveries for Suffolk and Nassau counties, the state of New York and numerous other New York counties the firm represents. The trial concluded in December 2021 with a plaintiffs’ verdict against opioid manufacturer Teva Pharmaceuticals and its subsidiaries and the distributor Anda, Inc.

Helping Child Abuse Victims

Jo Anna has worked tirelessly on behalf of sexual abuse victims located in Haiti and in the United States. In 2019, she helped achieve a landmark $60 million class action settlement on behalf of 170 Haitian boys harmed by a convicted pedophile and former school administrator associated with a Jesuit school in Connecticut. She stood by their side throughout the entire litigation process to help ease their burden.

“It’s important to look at a case from all angles with compassion and common sense,” she said. “I fight for people from all walks of life and dive into the details because I am determined to secure the best outcome for them.”

Protecting Neighborhoods and Towns

In the area of environmental litigation, Jo Anna has served as class counsel on behalf of victims against the largest industries, such as steel mills and refineries, whose negligence threatens the environment, groundwater and neighborhoods where neighboring residents live.

In 2014, Jo Anna helped lead the Bridgeton Sanitary Landfill litigation, where a federal district court approved a settlement that required the owners of the landfill to pay residents living near the site nearly $7 million.

In 2017, she served as class counsel for the Village of Roxana, Illinois, a small community outside of St. Louis, and surrounding properties. In this case, a lawsuit was brought against the Wood River Refinery and Shell Oil for the contaminated groundwater emanating from the refinery. This resulted in a nearly $6 million settlement for the Village of Roxana and area property owners.

In the same year, she served as class counsel and secured a $4.26 million settlement for a class action lawsuit on behalf of plaintiffs whose homes were polluted by emissions coming from a Granite City, Illinois, steel mill.

“Our clients can expect regular, consistent communication and a team approach,” Jo Anna said. “We will use every tool we have at our disposal to fight for them and to recover the justice they deserve.”
