Board Mourns Passing of Catherine Marcucci

THCA Mourns the Passing of Board Member, City of Industry Mayor Pro Tem Catherine “Cathy” Marcucci

The Tres Hermanos Conservation Authority Board of Directors and staff extend our deepest condolences to the surviving family and friends of Board Member Catherine “Cathy” Marcucci, who sadly passed away after a long hard-fought battle with cancer.  Cathy Marcucci, aged 60, passed away peacefully at her home surrounded by her family on Friday April 26, 2024.  She valiantly fought a three-year battle with aggressive anaplastic thyroid cancer. We share in their grief and offer our support and solidarity as we honor the extraordinary life of a truly remarkable leader.

A lifelong resident of Southern California, Cathy began her civic career in 2017 as a member of the City of Industry city council, where she served continuously, stepping into the role of Mayor Pro Tem in 2019.  She also continuously served on the Tres Hermanos Conservation Authority Board of Directors since it was re-established in February 2019 as a Joint Powers Agency with the cities of Chino Hills, Diamond Bar and Industry.

Throughout her tenure, she demonstrated exemplary leadership, championing causes that uplifted the lives of our citizens and our furry companions alike.  An avid animal lover, Director Marcucci’s dedication to animal welfare was unparalleled. She spearheaded efforts to establish the first no-kill animal rescue in the San Gabriel Valley, leaving an enduring legacy of compassion and kindness. As a Board Member, she proudly worked to help assist Red Bucket Equine Rescue in their animal rescue efforts.  Through her vision and determination, countless animals have found refuge and love, representing the spirit of hope that Cathy embodied.

Cathy is survived by her husband Steve Marcucci; daughter Lauren Eigel and son-in-law, Pete; parents, Larry and Etta Colson; brother and sister, Tim Colson and Chrissy Lowe, and their families; and countless dear friends. She is also survived by her rambunctious four dogs and two cats, all equally beloved and in no particular order: Nemo, Lola, Rosie, Louee, Lucy, and Laci.

To honor her memory, the City of Industry will host a celebration of Cathy’s life on Saturday, June 8, at 1 p.m. at the Industry Hills Expo Center (16200 Temple Ave, City of Industry, CA). We invite friends, family, and anyone who knew Cathy to attend and celebrate her wonderful life and legacy. Attendees are encouraged to wear bright colors to match Cathy’s vibrant spirit. Please bring your favorite photo and memory of Cathy.

In lieu of flowers, please consider donating to your local animal shelter or to Priceless Pets, an animal rescue and shelter with whom Cathy volunteered, helping to save dozens of cats and dogs throughout the West Coast. Memorial gifts to Priceless Pets can be found at

To know Cathy was to know love, compassion, and joy. Her caring heart, warm smile, and sparkling laugh will always be remembered.
