Shawn has led some of the most visible and wide-ranging national catastrophic wildland fire litigation cases of the past three decades. He has held Court Appointed leadership positions in multiple hundred million and billion dollar JCCP Mass tort actions.

He served as a court appointed Co-Lead Counsel in the tragic and disastrous 2017 and 2018 Northern California, Camp, Thomas and Woosley Fires. In 2020 alone, over $26.6 Billion was recovered as a result of effective and aggressive civil prosecution of the defendants in these cases. The Woosley Fire case was settled in 2021 for $2.2 Billion, along with the deadly Zogg Fire against Pacific Gas and Electric Company. During 2022 and 2023, Shawn negotiated resolution of several cases involving hundreds of millions of dollars in settlements, and in 2024, he has reached settlements exceeding $300 Million.

He successfully litigated his first wildland fire trial in 1996 against San Diego Gas & Electric for causing the 1993 Guejito Fire. Shawn promptly followed that trial with a lawsuit against Southern California Edison and obtained a 1997 verdict resulting in the recovery of millions of dollars for victims of the 1993 Winchester Fire.

In addition to recovering a multimillion-dollar settlement from the U.S. government for starting the 2002 Pines Fire that burned 62,000 acres, Shawn has obtained multimillion-dollar results in other wildland fire cases and has litigated against Alaska, Arizona, California, Idaho, Kansas, Nevada, New Mexico, Oregon, Tennessee, Texas, Utah and Washington public utility companies, electrical cooperatives, governmental agencies and irrigation districts.

Shawn served as co-liaison counsel for the insurance companies involved in the 2007 San Diego County wildland fire cases, which resulted in a recovery for the insurers exceeding $1.3 Billion.

In 2015, Shawn was Co-Liaison Counsel for the insurance companies and successfully helped resolve the litigation stemming from the 2011 Bastrop County Complex Fire, the most destructive wildfire in Texas history.

During 2016,  Shawn was engaged in resolving powerline-related fire cases totaling over $25 Million in recoveries including the $8.3 Million recovery from the Steiner Ranch litigation where Shawn was Co-Liasion Counsel.

Shawn is currently litigating cases on behalf of clients impacted by the destructive 2019-2023 wildfires in Alaska, California, Hawaii, New Mexico, Oklahoma, Oregon, Tennessee, Texas and Washington.
