Pleasanton, California

Lee Arthur Zachariades, lovingly known as “Zack,” passed peacefully at his home on January 13, 2026, with his loyal dog, Bailee, by his side.

Zack is survived by his daughters, Allie and Katie; their partners and husbands, Collin and Brandon; and his cherished granddaughters, Charlotte Grace and Harlan, who brought him immense pride and joy.

Born in Castro Valley, California on June 4,1949, to dedicated educators Katherine “Zacky” Zachariades and George Zachariades both immigrants from greece, Zack was raised in the Greek Orthodox faith and served as an altar boy. He lost his father at age 12, a formative event that shaped his character and resilience. Though an only child, he shared a lifelong bond with his cousins Bill, Deb, Liz, and Art, spending treasured summers together in Massachusetts and Maine.

A natural leader, Zack was class president at Canyon High School and went on to earn a degree in History from UC Berkeley. He played football for the Cal Bears during his college years, and remained an enthusiastic fan throughout his life. Being the son of two educators, he was drawn to teaching and went on to earn his teaching credential. He landed his first job as a 5th grade teacher at Alisal Elementary, and continued to dedicate 45 years to the Pleasanton School District as a teacher and coach. He was known for his wild sense of humor and unique classroom spirit. He believed deeply in young people and worked tirelessly to create environments where students felt seen, supported, and valued. Through breakfast clubs, BBQs, field trips, and school events, Zack built havens where students could explore their identities and discover their self-worth. Many lives were forever changed because Zack chose to care, to show up, and to lead with integrity, heart and some.

Zack shared a love of the outdoors, sports, and community with Joanne, with whom he raised two daughters in Pleasanton and Lake Tahoe. He was deeply devoted to his children, always present for their challenges and achievements.

In retirement, Zack found joy in golf, fishing, gardening, time with friends, and long walks with Bailee. He was steadfast, loyal, passionate, and unapologetically real. Zack will be deeply missed.
