Ashley Campbell

Counsel, Sher Edling LLP


Ashley applies the power of law to protect the planet by promoting sound science and amplifying the voices of scientists. She represents California, Hawai’i, New Mexico, Oregon, Rhode Island, and Washington in litigation against the manufacturers of PFAS (per- and poly-fluoroalkyl substances). She has worked on hundreds of other similar cases across the country on behalf of public water systems. She currently serves as co-chair of the water provider subcommittee as well as member of the sovereign subcommittee of the Aqueous Film-Forming Foam Multi-District Litigation (MDL No. 2873).
Ashley focuses her practice on complex environmental contamination litigation. She has represented clients before municipal boards, state committees, and state courts, has drafted appeals to the New Hampshire Supreme Court, and briefs to the Ninth Circuit Court of Appeals, and the U.S. Supreme Court.

Before entering private practice, Ashley was a law clerk with the New Hampshire Superior Court for three years working with judges across the state. In that role, she worked on the record-setting New Hampshire MTBE (methyl tert-butyl ether, a gasoline additive that contaminated New Hampshire’s water resources) litigation, including its four-month jury trial, dispositive motions, limine motions, and post-verdict motions.

Ashley has been recognized as a Super Lawyer, Super Lawyer Rising Stars, and was honored with the New Hampshire Bar Association’s Pro Bono Honor Roll, and Union Leader’s 40 Under Forty, Class of 2018. Ashley serves on the Board of Girls on the Run NH. When Ashley isn’t working to protect our planet, you can find her getting muddy on some trails, training for an ultra-marathon.
