OBITUARY
Sandy Jonas passed away peacefully at the age of 78 on February 7, 2026, surrounded by her loving husband, Bruce, and some close family members. She was a proud second generation Italian who was born and raised in Santa Rosa.
Sandy attended Roseland Elementary School, Cook Jr. High, and graduated from Montgomery High School in 1966. Shortly after, she was hired by Wells Fargo Bank to be an executive secretary to Harry Nielson. She and Harry were in charge of setting up the Mastercard roll-out for the West Coast. In 1983, she and her husband, Bruce, co-founded Jonas Optical, and in 1995 Sandy followed her passion of music and began teaching piano lessons. She was an advanced teacher of piano theory and found great joy in preparing her students for their spring and winter recitals each year.
Sandy was a member of the National Guild of Piano Teachers and she always looked forward to her annual trip to Mendocino with Bruce to attend the Mendocino Music Festival. Other places Sandy and Bruce enjoyed traveling to include Hawaii, San Diego, and Phoenix to visit family.
Sandy was a devoted member of St. Mark Lutheran Church. She was a lover of all animals and she enjoyed gardening, swimming, and square dancing. She was an incredible Italian cook (and baker) who liked entertaining. Her lasagna was legendary and people who knew Sandy well looked forward to her homemade biscotti every December.
Sandy is survived by her husband of 53 years, Bruce Jonas, her brother-in-law, David (Gloria) Jonas, sister-in-law, Sharon Jonas, cousins, Linda Brodie, Claudia Willow, and Dennis Wolcott, and numerous members of her extended family.
Sandy is preceded in death by her parents, Joseph & Doris Ariasi, cousin, Angie Williams, niece, Dr. Diane Beach, brother-in-law, Reverend Herman Jonas, and great-nephew, Jackson Williams.
