Bonnie M. Leach

Bonnie Marie Leach, née Stone, passed away peacefully on May 30, 2026, at the age of 89.
Bonnie was born in Phoenix, Arizona, and spent more than 40 years in Tustin, where faith,
family, friendship, and community were at the center of her life. A lifelong Catholic, she spent
three decades working at Holy Family School, where she became a familiar, welcoming
presence to generations of students, parents, and staff.
Bonnie was preceded in death by her beloved husband, Frank Leach. She is survived by her
children, Dr. Timothy Leach and his wife, Teresa Leach; Susan Glenane and her husband, Ron
Glenane; and Kristina Leach and her husband, Eric Person; her cherished grandchildren, Laura,
Regan, Emma, Aidan, Maeve, and Isaac; and her younger brothers, Don and Jeff Stone.
Family was the heart of Bonnie’s life. She loved her grandchildren more than anything in the
world, followed their lives with pride, delighted in their accomplishments, and treasured every
moment she spent with them.
Bonnie’s generosity, humor, and love of family shaped the lives of everyone fortunate enough to
know her. She will be deeply missed and forever loved.
Family and friends are invited to celebrate Bonnie’s life at a Funeral Mass at 11:00 a.m. on
Friday, June 19th at St. Catherine of Siena Catholic Church, 1042 Temple Terrace, Laguna
Beach, California.
