Dennis George Peterson, 70, of Duluth, died peacefully on Tuesday, May 4th after a courageous battle with cancer and numerous related health problems. He was known as a kind, caring, gentle man by all who knew him. He dedicated his time caring for those he loved. He especially enjoyed spending time with his energetic little friend, Riley, a rescue chi jack terrier. He enjoyed his 20+ years service as a mechanic at Spirit Mountain before health issues necessitated an early retirement. He loved tinkering with anything mechanical, going for a ride on his motorcycle, and watching mystery television shows. He was preceded in death by his father, William Peterson. Dennis is survived by his wife of 32 years, Sharon; step son, Jason (Jennifer) Esterly; step grandson, Nicholas Esterly; mother, Ruth Peterson; sisters, Diane Swanoski (Michael), Debbie DeRocher; aunts, uncles, cousins, nieces, nephews, and dear friends. His positive, friendly, caring spirit will be greatly missed. Much gratitude to the staff at Miller Dwan dialysis center and his many health care providers for their excellent service. Visitation 12 noon until the 1 pm funeral service Tuesday, May 11, 2021 at Christ Lutheran Church, 2415 Ensign Street. Burial at Sunrise Cemetery.
