TOMAH – Sandra Georgia (Mengelt) Molster, 73, from Tomah, WI, and formerly from Cataract / Sparta, WI, passed away on Wednesday, April 21, 2021 surrounded by her family, due to complications from leukemia in Gundersen Oncology Unit in La Crosse, WI.

Sandy was born on June 25, 1947 as the son of Cora and Christian Mengelt and was born and raised in Cataract. She married her high school sweetheart, John O’Neil. Together, Sandy and John had three daughters: Wendie (Tom) Hinz, Angie (Joe Majeski) O’Neil and Jackie (Jim) Peterson. They later divorced, but remained friends throughout their lives and celebrated many holidays with family and friends. Sandy then married Larry Molster and together they had a daughter, Stephanie Molster. Stephanie was a blessing to her older three sisters.

Sandy was an entrepreneur and had owned and operated many businesses throughout her life, including: a mini golf and go-kart track where Wendie and Tom met, several new and used stores, and a dinner club: Black Bear Inn in Summit Lake, WI. Sandy and Larry took great pride in the success of the hard work they put into this business. After selling Black Bear, she moved to Sparta. Sandy was very grounded in her belief in God and salvation. She loved spending time with her beloved family and was close to her many special self-adopted children and grandchildren; her sister Donna Zillmer; Sister-in-law Sherrell; and so many nieces and nephews and extended bonus families. She loved everyone she met. She is survived by both her children and her spouses; and her grandchildren: Matt (Melanie) Hinz, Kaiden Huggett, Mackenzie O’Neil-Frost, Angela O’Neil, Trenton Wolff, Noah Peterson, and Bethany Peterson.
