He was a kind and humble man. Not a mean bone in his body. He loved his family and friends, and will be so missed. He also loved his work. He never did “officially” retire. He would’ve rather been at work than anywhere else. He was “at work” until his passing. He also had a quiet sense of humor!

A grave side service will be held 10:00 a.m., Tuesday, August 4, 2026, at the Custer Cemetery in Custer, SD. Immediately after the family invites you to join them for a luncheon at the Rushmore Brewing Company, 140 Mt. Rushmore Rd, Custer, SD.

Honorary pallbearers are all of you out there who were taught to be lineman by the best!
