Mark Patrick Henneberger

Mark Patrick Henneberger, 69, of Bentonville, Arkansas passed away on April 7, 2026 with his loving family by his side after a years-long battle with lung cancer. Even in his darkest, hardest moments, he always stayed true to himself, a clever, stubborn, grumpy fighter until the end.

The only son of Frank and Patricia (Hogan) Henneberger, Mark was born on February 17, 1957 in Detroit, Michigan. A quick-witted, hard worker, he graduated from East Detroit High School before heading to Eastern Michigan University, where he met his first wife Sue. It’s also during this time at Eastern that he started working on local sets with his dad, washing cars and piquing a lifelong passion.

Mark had a prolific and storied career, rising through ranks at agencies in Detroit, before moving to Northwest Arkansas in 2006. It’s there he started working for Walmart and was the driving force behind some of the most well-known events in the area. He was truly one-of-a-kind at what he did.

The stories from the events were limitless and captivating, full of wit and charm and a frank matter-of-factness. He took tremendous pride in what he did, but was never boastful, even with his vast accomplishments. During an event, you could find him in the back of the room, deeply invested in his work without ever wanting to be the center of attention. That commanding, stoic demeanor made him a valuable mentor to hundreds of people, impacting so many with his knowledge and wisdom and leaving a profound, lasting legacy.

In his spare time, he was an avid golfer, with a few career highlights: winning the doubles tournament at Dearborn Country Club, hitting a hole-in-one while playing at a celebrity Pro-Am and playing at Augusta National. Mark couldn’t resist a good bourbon, even better wine and an Oberon on the boat in Michigan.

He loved Detroit sports almost as much as he loved his family. Watching the Red Wings from the upper bowl of Joe Louis Arena in the early 80s to powerhouse dynasty in the late 90s; yelling at Michigan on Saturdays and the Lions on Sundays; ranting about how Michael Jordan ruined the Bad Boys. Thankfully, Mark wasn’t disappointed in the final Detroit sports game he got to watch - the University of Michigan winning the National Championship.

Before Sue’s passing in 2020, they raised their daughters, Erin and Katie, in a house full of love and humor. They were generous and passionate, tough yet kind, never wavering in their love and support.

In 2022, Mark was set up on a blind date with Gina by a close mutual friend, and the sparks were immediate. With their relationship, he regained a spirit and joy that had been lost. They traveled, they had adventures, they built a life together. With her kindness and generous spirit, she helped care and fight for him throughout his cancer diagnosis, which came just a few short months into their relationship.

The couple married on Monday April 6, in an intimate and unconventional ceremony, a beautiful final act of love, different from what they would have ever dreamed or planned but filled with love and joy all the same.

He is preceded in death by his father Frank, mother Patricia, first wife Susan (Savel), and the best dog in the world, Luigi.

He is survived by his wife Gina Henneberger, his two daughters Erin Henneberger and Katie Giess; step (bonus) daughter Kara Bonds; his sons-in-law Nick Jury, Matt Giess and Josh Bonds; three grandsons, Cameron, Noah and Harry; and granddaughter Brianna.

A celebration of life will be held on April 19 from 1:00-5:00pm at 21C Hotel in Bentonville, Arkansas. In lieu of flowers, please consider donating to the St. Jude Children’s Hospital.
