It is with great sadness that the family of Frank Engberg Lassen announce his passing on Friday September 25, 2026 at the age of 93 years. He was born on March 16, 1933, to Karl Ingberg Lassen and Anna Mathilde Lassen (nee: Hansen) in Arhus, Denmark.

A cherished husband preceded in death by his beloved wife Lis Lassen (nee: Højlund), they were married on November 29, 1958 beginning a happy and enduring union that lasted 66 years.

Their connection was strong, and they soon became inseparable, sharing long walks, dancing, gardening, camping, fishing and traveling to explore the mountains and the world.

Frank is now with his wife Lis, and lovingly remembered by his sons Dennis Lassen (Susan Nisula), Eric Lassen (Kathleen Duchesneau). A beloved Grandfather, Frank will be greatly missed by his four grandchildren Nathaniel, Mikayla, Victoria, and Alexandra Lassen.

Frank will be privately laid to rest with Lis in Mountain View Cemetery, Lethbridge, Alberta.
