William Spenser Twomey was called home too soon on December 16, 2025, at the age of 38, in League City, Texas.

William was born on August 5, 1987, in Houston, Texas. He grew up in the Clear Lake area and attended schools in the Pasadena Independent School District, graduating from Pasadena Memorial High School in 2006. During his time there, William made history as the school's first mascot and served as vice president. He continued his education at Houston Community College.

William later moved to Katy before settling in League City to be closer to his family. He had a strong passion for logistics and began his career with Walmart, eventually working for several logistics companies where he gained valuable skills and experience.

Known for his strong work ethic and determination, William faced life's challenges with resilience and perseverance. He had a gentle spirit and was often remembered for his contagious giggle. William brought light and laughter to those around him and embraced life with energy and joy.

Affectionately nicknamed "Mad Dog" by his friends, William loved country music and dreamed of mastering country western dance moves. He enjoyed spending time with friends—whether grabbing a bite to eat, enjoying his favorite drink, or playing video games. A devoted sports fan, he especially loved cheering on the Green Bay Packers and the Houston Rockets. Ever dedicated and thoughtful, William even taught himself Spanish to better communicate with his coworkers.

Though William never married, he was deeply loved and is survived by a large and caring family and many cherished friends.

William is survived by his mother, Connie Kaisler (Craig Barton); his brother, Alec Twomey; his sisters, Miranda Twomey (Curtis Cooper) and Mia Twomey; his grandfather, Dennis Kaisler; his nephews, Weston Cooper and Wyatt Cooper; his uncle, Joseph Kaisler (Christy Torres); his aunts, Lisa Zepeda (Vernon Zepeda) and Dawn Poole; and many cousins, including Gabriel Kaisler, Elizabeth Kaisler, Christopher Kaisler, Cathy Kaisler, Samantha Kaisler, Daniel Zepeda, Aaron Zepeda, Joey Enriquez, Samantha Padilla, Angela Smith, Ricky Poole, and Rachel McMeekin.

He was preceded in death by his father, Bill Twomey; his grandmothers, Mary Kaisler and Carolyn Twomey; and his uncle, Richard Poole.

In lieu of flowers, the family asks that donations be made in William's memory to the Epilepsy Foundation or a local homeless coalition.
