Cassie Marie Nielsen Todorovich

Cassie Marie Nielsen of Superior, Wisconsin, passed away on November 25, 2025, at Essentia Health in Duluth, Minnesota at 43 years old. Cassie was born on December 9, 1981, in Grand Rapids, Minnesota, to Kjersti Kannas and Gary Nielsen.

“Cass,” as many called her, is survived by her mother, Kjersti; her sons, Conner and Tyler Kassler of St. Paul, Minnesota; her fiancé, Frank Anderson of Superior, Wisconsin; her brother, Chad Nielsen of Grand Rapids, Minnesota; her sisters, Codi Couchman of Richland, Washington and Vanessa Eichorn of Grand Rapids, Minnesota; her ex-husband, William Todorovich of Superior, Wisconsin; and many aunts, uncles, nieces, and nephews. She was preceded in death by her father, Gary Nielsen, and her grandparents, William and Maryann Nielsen and Charles and Juanita Kannas of Bovey, Minnesota.

Cassie had a passion for the outdoors and found peace on the water with a fishing rod in hand. Whether casting a line on a river or sharing stories with her fishing buddies , she cherished every moment spent fishing. She was also a devoted Minnesota Vikings fan who never missed a game, cheering on her team through every season.

Those who knew Cassie well understood that she had a fiery, stubborn side—she was strong-willed and never afraid to speak her mind. Yet this same fierce spirit made her an incredibly loyal friend and protector of those she loved. Despite her stubborn streak, Cassie would drop whatever she was doing at a moment’s notice to help someone in need. Her family and friends often remarked that she would give a stranger her last dollar if they needed it. Cassie’s combination of strength and compassion made her unforgettable to all who crossed her path.

Cassie will be forever missed by all who knew and loved her.

There will be a Celebration of Life sometime next summer.
