COTTAGE GROVE / STOUGHTON - Lisa Marie Moriarity, 41, passed away unexpectedly on Tuesday, August 18, 2026, following complications from surgery and ongoing health issues. She was born September 2, 1984, in Madison, to Steve Killerlain and Shawn Moriarity.

Lisa graduated in 2003 and earned her CNA certificate from MATC. She held various positions in customer service and health care, though her true passion was caring for others. That compassion was evident when she put her own life on hold to care for her mother following her terminal cancer diagnosis in 2016. After her mother's passing, Lisa devoted herself to caring for her father until his passing in 2023.

Lisa was a beloved mother, daughter, sister, aunt, soon-to-be gigi, and friend. Above all else, she was a mom. Her children, Sierra and Cain Brummer, were her whole world. There was nothing Lisa was more proud of than her children, and being their mother was her greatest accomplishment and the role she cherished most.

Lisa was one of the kindest souls you could ever meet. She was the type of person who would give the shirt off her back to anyone who needed it, never hesitating to help someone she loved.

Lisa is survived by her children, Sierra and Cain Brummer; Sierra’s fiancé, Zachary LaFrombois, whom Lisa loved as her own; her children’s father, Lukas Brummer; her sister, Sarah (Victor) Laws; her niece and nephew, MadiLynn and Conner Killerlain; and many extended family members and dear friends who will forever carry her memory in their hearts.

She was preceded in death by her parents, Steve and Shawn; paternal grandparents, Jerry and Joann; maternal grandmother, Jeanne; as well as other loved ones who undoubtedly welcomed her home with open arms.

Lisa’s passing was sudden and unexpected, leaving behind a tremendous amount of love, heartbreak, and memories. Though her time with her family was far too short, the love she gave them will continue through her children, her future granddaughters, and everyone whose life she touched.

Rest peacefully, Lisa. You were the best mom, the kindest soul, and you were so deeply loved. Your kids were your whole world, and there is no doubt that you were theirs.

A celebration of life will take place at VFW POST 7591, 301 Cottage Grove Road, Madison, from 1 p.m. until 5 p.m. on Saturday, September 5, 2026.

In lieu of flowers, memorials may be made to Lisa’s children for use to be decided at a later date. Online condolences may be made at www.gundersonfh.com.
