Sandra F. Grenke

Sandy was born in Gillett, Wisconsin on February 20, 1940. She grew up in a farming family. From a young age, she knew she wanted to be a teacher. Her career in education spanned over 40 years, most of which she devoted to supporting struggling readers in Title I programs. She earned multiple degrees and was honored with a nomination for Regional Reading Teacher of the Year. In addition, Sandy took on a program known as ‘Rock and Read’, where new parents received a book for their child along with learning the value of reading to children from the start of life. Beloved by her school community, Sandy was known for her kindness and for always offering help to any child or colleague in need.

Sandy married Herbert Grenke on August 26, 1959. Their love spanned 66 years. As the wife of Coach Herb, Sandy was a true partner both at home and from the stands. She warmly opened her home to staff and players, many of whom thought of her as a second mother while away at school. Quiet by nature, Sandy nonetheless could be heard cheering boldly from the sidelinesäher ‘Get them!’ echoing at countless games. She shared many special memories with the coaches’ wives, friendships she maintained long after Herb’s retirement.

Faith was a cornerstone of Sandy’s life. A devoted member of Messiah Lutheran Church, she participated in Women’s Circles, prepared layettes for those in need, and welcomed new members with open arms. She believed deeply that all people are beloved children of God, and she lived out her faith with kindness, inclusivity, and grace. Above all, Sandy was a loving and fiercely protective mother and grandmother. She was a tireless advocate for her daughter Stephanie through a long battle with mental illness, and though Stephanie’s passing was a heartbreaking loss, Sandy quietly offered compassion and support to others in the community facing similar struggles.

Her daughter Liz, also a teacher and Reading Specialist, often turned to Sandy for encouragement, ideas, and wisdom. Sandy took great joy in Liz’s marriage to Bill, carefully arranging every detail of their beach wedding-including the flowers, which she loved dearly.

Her greatest delight came from being ‘Grandma Sandy’ to her grandchildren, Everest and Charlotte. She was devoted to them from the moment they were born, rarely missing a concert, play, or milestone. Family trips to St. George Island, Florida were filled with adventure and laughter, and time spent at Grandma and Grandpa’s home in Marquette was always special. Watching Everest and Charlotte grow into young adults filled her with immense pride and joy.

Sandy treasured her friendships and was blessed with many close companions. She especially cherished her group of friends affectionately known as the ‘Bungaritas,’ who shared life’s joys, supported one another in challenges, and created a bond filled with love and laughter. She also remained active in book clubs and educational groups, continuing to learn and give to her community.

Recently, Sandy and Herb spent time at Liz and Bill’s cottage in New Mexico, where she painted the desert and mountain landscape, crafted sage bundles with wildflowers for friends, and faithfully tended to the hummingbirds she adored.

Sandy is survived by her husband, Herb Grenke; daughter, Elizabeth (Liz) Grenke Leach; son-in-law, William Leach; and grandchildren, Everest Emerson Grenke Leach and Charlotte Avalon Grenke Leach. She is also lovingly remembered by many nieces and nephews.
