It is with heavy hearts we announce the passing of John Thomas Sines who peacefully transitioned on March 10th, 2024 after a valiant two-year battle with Glioblastoma brain cancer. John maintained his strength, humor, and courage throughout his journey. Every day was a battle to enjoy even one more minute in his beautiful life. He is survived by his devoted wife, Gail, their two adoring children, Conner Sines (California) and Veronica Lowry with her husband Ryan Lowry (New York); two sisters, Jo Ann Swiger (Texas) and twin sister, Betty Sines (California); niece, Cheryl Squires (California), and his extended family and many loving friends. John is preceded in death by his parents, John Sidney and Caroline Sines.

John was loved by all who were lucky enough to know him. His kindness, compassion, and quick wit buoyed everyone around him during the hardest of times. John enjoyed a lengthy career as the top finance executive for multiple high-tech companies in and around Silicon Valley but it was his passion for Plein Air painting that truly made his heart sing. John’s legacy is marked by the love of his family and friends, his love of art and beauty, and his ability to masterfully reflect those emotions in his beautiful paintings. John will be sorely missed but his love and his paintings will always be with us.
