David Mark Sather

David "Mark" Sather, age 71, of Centreville, Virginia, passed away peacefully on March 10, 2026, at Inova Alexandria Hospital in Fairfax County, with his loving family by his side.

Mark was born on August 17, 1954, in Hanover, Pennsylvania, to Roger L. Sather and Patricia A. Pfoutz. At the young age of 17, he proudly enlisted in the United States Navy, serving from 1972 to 1975 with 2 years and 9 months at sea, earning a National Defense Service Medal and a Meritorious Unit Commendation for his dedication. After his military service, Mark became a skilled engineer, capable of fixing any household challenge, while building a life rooted in love, commitment, and family.

Mark was an avid D.C. sports fan, a lover of everything to do with Harley-Davidson motorcycles, and an antique collecting enthusiast. He was a true friend to neighbors and many others, always ready with a story, a "dad joke", or a helping hand. A devoted Catholic and family man above all, Mark placed his loved ones at the center of his world.

Preceded in death by his parents, Mark is survived by his devoted wife of 23 years, Pura; children, David (Heather), Matthew (Cristina), Marcelo, and Stephanie; grandchildren, Katelyn, Aedan, Grace, and Noah; brother Michael; nephews, Jason and Samuel; and his beloved pets, chocolate lab Rosie and bird Beau-all whom he loved dearly.

Mark will be deeply missed by all who knew and loved him. The family finds comfort in knowing Mark is now at peace in the loving presence of the Lord.
