Margaret "Peggy" Helen (Simpson) Weak

It is with heavy hearts that Patrick and Brendan Weak announce the passing of their beloved mother and hero, Margaret Helen (Simpson) Weak, known to all as “Peggy.” Peggy passed away unexpectedly yet peacefully at her home in Moorpark, CA, on August 19, 2025, at the age of 79.

Peggy was born on March 17, 1946, to Jane (Perry) and John Simpson in Inglewood, CA. She attended local schools and graduated with the class of 1964 from Morningside High School. She went on to study at El Camino Community College before transferring to San Jose State University, where she earned her Bachelor of Arts degree in Education.

After college, Peggy returned to Southern California to begin what became a 30-year career as an elementary school teacher. She first taught at Washington Elementary in Lynwood, CA. In 1979, she stepped away from the classroom to pursue her greatest dream—starting a family. Peggy and her beloved husband, James “Jim” Weak, moved to Moorpark in 1981 with their two young sons.

In addition to her cherished role as a mother, Peggy gave back to her community through free tutoring for underperforming students and by playing an integral part in her husband’s political career in Moorpark. When Jim was diagnosed with an aggressive form of leukemia in 1986, Peggy devoted herself to his care until his passing. Widowed with two young boys, she returned to teaching full-time to support her family.

Over the next 25 years, Peggy taught at Peach Hill and Walnut Canyon Elementary Schools in Moorpark. There she found a village of support around her—colleagues who became lifelong friends, and students and families who claimed her as their own. A passionate reader and educator, Peggy spearheaded the creation of the Peach Hill Posse reading program, which inspired students to collectively read more than one million minutes each school year and, more importantly, sparked a lifelong love of reading in countless children.

Beyond her professional life, Peggy found joy in gardening, crafting, and creating lasting memories with family and friends. She embodied the true spirit of a teacher and mother—leading with love, empathy, and compassion, while remaining principled and steadfast in her belief in standing for humanity and what is right. Peggy’s life left an indelible mark on all who knew her, and we are forever grateful to call her our friend, colleague, teacher, and mother.

Peggy was preceded in death by her loving husband Jim, her parents John and Jane Simpson, and her sister Linda (Simpson) Liken. Peggy is survived by her brother Don Simpson; her sons Patrick and Brendan; daughter-in-law Lindsey; and her cherished grandchildren Quinn, Harrison, and Emmy. She also leaves behind many nieces, nephews, and countless others who affectionately recognized her as their second “Mom.”

Funeral services will be held at 10:00 a.m. on Friday, September 12, 2025, at Pierce Brothers Valley Oaks-Griffin Memorial Park in Westlake Village. A reception will follow at the Weak residence in Moorpark.
