In Loving Memory of Ilse von Hochlandenge
 My beloved Director of Security and Official Greeter, Ilse, will always hold a special place in my heart. Known for her loyalty, warmth, and ability to brighten every client’s day, Ilse welcomed everyone with a friendly spirit that perfectly reflected my company’s values. Though she has passed, her presence continues to be felt in the joy she brought to my office and the countless smiles she inspired. She will forever remain a cherished part of my story.
