    I was deeply saddened to hear about the passing of Mark Demore. Working with Mark was truly an honor. Mark carried himself with a quiet strength, a steady dedication, and a genuine commitment to serving our Veterans and supporting his colleagues. He was someone you could always count on—whether it was answering a question, stepping in to help, or offering calm guidance when challenges arose. Mark made a lasting impact not just through his work, but through the kindness and respect he showed everyone. His presence brought a sense of reliability and warmth to every project and every interaction. He will be profoundly missed by all who had the privilege of working alongside him. My thoughts and deepest sympathy are with his family, and all who loved and cared for him. May they find comfort in knowing how much he was valued and how far his influence reached. Mark's legacy of service and integrity will not be forgotten.
