Dennis K. Gustafson, age 80, of Farmington, passed away on February 10, 2026. He was preceded in death by his parents, Ernest and Eunice Gustafson, and his son-in-law, Chris Ostertag.

Dennis is survived by his wife, Mary; his children, Tom Gustafson and his wife Gina, Kathy Ostertag, and Stacy and her husband Todd Ratzlaff; his grandchildren, Kyle, Kelly, Matt, Gracie, Joe, Jake, and Alexa; and his great-grandchildren, Hadley, Elsie, Brody, and Emma. He is also survived by his sister, Connie Gersich, and her husband Ed, as well as other loving family and friends.

Dennis, also known as Punky, was a lifelong barber and the owner of Park Lawn Barbershop in Edina. He was an avid sports fan who followed all Minnesota sports, but nothing brought him more joy than watching his grandchildren grow up playing sports. He cherished time spent at the cabin in Nashwauk, Minnesota, and was deeply proud of his Iron Range heritage.

Dennis will be greatly missed by all who knew and loved him.

A celebration of life will be held at the Rosemount American Legion on Wednesday, February 18, 2026, from 4:00 to 7:00 p.m.
