Deborah Marie Siefert
March 5, 1951 – July 19, 2025
With heavy hearts, we announce the passing of Deborah Marie Siefert, who left us on July 19, 2025, at the age of 74. A devoted daughter, loving sister, proud mother and grandmother, friend and independent soul, Deborah touched the lives of many with her kindness, strength, and selfless spirit.
Born on March 5, 1951, Deborah lived a life filled with purpose, laughter, and love. She proudly served her community for 25 years at the Muskego Post Office, where she was known for her reliability, warm smile, and dedication.
Deborah was the proud mother to two children, Mark and Denise (Alan), and a deeply devoted grandmother to Sara, Sam, and Ethan. She found immeasurable joy in her role as “Grandma,” always offering encouragement, support, and unconditional love. Her family was the heart of her world.
She was also a cherished daughter and loving sister, always there when needed, offering quiet wisdom, unwavering support, and a steady presence. She was preceded in death by her father, Clifford Heise, and is survived by her mother, Eleanor Heise, her children, Mark and Denise (Alan), and her siblings, John (Kathleen), Arlene (the late Gregory), and Scott (Cheryl). She was a beloved aunt to her loving nieces and nephews, who brought her great joy.
Debbie had a natural talent for building things and a passion for doing things on her own terms. She was creative, resourceful, and never afraid to tackle a new project. Her independence was matched by her generosity – always ready to lend a hand or a kind word to anyone in need.
She found joy in the simple pleasure of life – singing, bowling, hunting, and fishing. Her laugh was contagious, her stories unforgettable, and her presence a comfort to all who knew her.
Deborah will be remembered not only for what she did, but for who she was: kind, caring, and selfless – a true example of strength and love.
Her legacy lives on in her children, grandchildren, family, and all the lives she touched.
She will be deeply missed and forever loved.
