Mark G. Nietzel

Mark G. Nietzel, 62, of Mentor, Ohio, passed away suddenly on March 6, 2026. He was born on June 12, 1963, in Willoughby, Ohio, to Dorothea Nietzel and the late Gunther Nietzel.

Mark was the loving husband of 35 years to Kristine Nietzel, devoted father to Robert Nietzel (Makenzie), and proud grandfather to Teddy. He was the beloved brother of Daniel Nietzel (Audrey), cherished grandson of the late Mary and Ludwig Onigkeit, loving brother-in-law to Sandy Escandon (Dan) and Shirley Veness (Mered), and the cherished son-in-law of Toby Petersheim and the late Katie Petersheim. He held dear his niece Ana and nephews Eddie (Noel), Dominic, Mario, and Gino (Jazmynn). He was preceded in death by his brother-in-law Ed Colavecchio.

Forever a child at heart, Mark found joy in simple adventures and everyday moments that became lifelong memories. He cherished family vacations to Hilton Head, neighborhood explorations with his young son and nephews using walkie-talkies, and his well-earned reputation as the best grill master around. Known for his playful, fun-loving sense of humor, he had a special gift for finding the lighter side of life and bringing smiles to everyone around him.

Mark dedicated 40 years to Manhattan Deli, a local spot he loved dearly, where he served as general manager. To him, his coworkers and regulars became his second family, and the friendships he built there were among the most meaningful parts of his life. He will be lovingly remembered and deeply missed by his family, extended family, and many dear friends.
