Renate was a woman of generous spirit, steady devotion, and joyful energy. She gave of herself freely through volunteer work, helping at hospitals, food banks, and churches. Her commitment to her community was also reflected in her leadership, serving as chairman of the St. John the Evangelist Church Festival and the Home and School Association. She embraced life’s simple and happy pleasures, enjoying walks, crocheting, live music, dancing, and animals, especially dogs and penguins.

For 34 years, Renate was a military wife, a role she filled with strength, loyalty, and grace. She also served as an Army Support Group Leader, offering encouragement and support to others and helping build connection among military families. In every part of her life, she brought warmth, dedication, and a caring heart.
