Katherine (Katie) Costa, passed away peacefully on July 15, 2021, in Santa Barbara, California at the age of 85. Born to Manuel and Frances Domingos, Katie was the 8th of 9 children, and was raised in the rural outskirts of Lompoc, California. Growing up on a dairy farm, Katie spent many mornings up early to milk the cows, before heading out on the bus to town for school. Katie attended Lompoc High School, where she played the saxophone in the band.

In the summer of 1953, Katie married the love of her life Frank Costa, Sr. and was blessed to raise her three children on the Costa Ranch in Drum Canyon surrounded by family and friends. Katie worked for 26 years as a Rural Letter Carrier, oftentimes taking her children along, sitting “shotgun” to get the chance to put the mail in each box on her route.

Well known for her artistic talent, Katie taught Tole Painting both locally at Allan Hancock College, as well as nationally at conventions that allowed her and Frank to travel to exciting destinations with friends. Katie’s work has been displayed at The White House, as well as the Smithsonian as part of the National Society of Tole & Decorative Painters collection. Also talented in-home arts, Katie’s rum cake was known for bringing smiles to family and friends social gatherings. She earned many awards throughout the years for her many artistic skills at the Santa Barbara County Fair.

Proud of her family’s Portuguese heritage, Katie was an active member of the Lompoc Pentecostal Association, making beautiful dresses and capes for her children and grandchildren throughout the years.
