Born on December 29, 1938, in Tampa, Florida, Sandra graduated from Hillsborough High School and attended Florida State University.
Sandra embodied beauty, grace, elegance, and southern charm. She had a warm heart filled with love for her family and friends and truly enjoyed visiting, whether in person or over the phone. An exceptional cook and gracious hostess, she had a special way of making everyone feel welcome, included, and loved around her dinner table. She will be remembered for her kind and loving spirit and her beauty, inside and out.
Her three daughters would like to extend their heartfelt thanks to everyone who prayed for their mom and for the love, kindness, and support shown to Sandra and their family throughout the years.
The family would like to express their sincere gratitude to Merviani Gonzalez and Clara Caliz for the loving care and compassion they provided to Sandra. They also extend their heartfelt thanks to Sharon Toro of LifePath Hospice and the entire staff at The Health Center at Canterbury Tower for their exceptional care and support.
A funeral Mass will be held on December 11, 2026, at 10:00 a.m. at Christ the King Catholic Church, with a reception to follow at Palma Ceia Golf and Country Club.
In lieu of flowers, donations may be made in Sandra’s memory to LifePath Hospice or the Alzheimer’s Foundation of America.
