Sandy's Donuts Co-Owner Mark Ostlund Passes Away at 62

A Legacy Defined by Buttermilk and Persistence

The regional landscape of North Dakota’s bakery scene has lost a central figure. Mark Ostlund, the 62-year-old co-owner of Sandy’s Donuts, passed away due to health complications, leaving behind a business that transformed from a neighborhood shop into a fixture of eastern North Dakota and western Minnesota. His son and current CEO, Jeff Ostlund, confirmed the news on the company’s Facebook page Friday evening, noting that his father had been battling health issues stemming from a heart valve condition that required open-heart surgery earlier in 2025.

For those who have followed the evolution of Sandy’s Donuts, Mark’s passing marks the end of a pivotal era. As reported by The Forum, Mark had spent much of his life guiding the business his parents, Sandy and Donna, launched in 1983. He was not merely a manager; he was the primary steward of a family legacy that began in a small kitchen in Tioga, North Dakota, where the elder Sandy Ostlund first learned to fry buttermilk doughnuts in a cast-iron pan over a coal-burning stove.

Growth Through Generational Transition

The story of Sandy’s Donuts is one of intense, hands-on development. When the shop first opened in a former West Fargo bakery, the work was grueling. It was not uncommon for the founders to sleep in sleeping bags in the back room just to keep up with the production demands of their growing customer base. Mark, who famously left college to join the family trade, viewed himself as the protector of this labor-intensive craft after his father passed away in 2008.

His confidence in the product was legendary, particularly during the regional expansion of national chains. In 2002, when Krispy Kreme entered the Fargo market, industry observers wondered if the local institution would be eclipsed by the massive marketing machinery of a global doughnut giant. Mark’s response was characteristically direct:

All the talk about doughnuts. All the hype. It just makes people want to buy doughnuts more. And I have better doughnuts.

He was right. While the Krispy Kreme location shuttered five years later, Sandy’s Donuts continued to scale. By its 40th anniversary in 2023, the operation had grown to employ approximately 100 people and produced between 6,000 and 16,000 doughnuts daily. The logistics of this output are significant, requiring a 12-to-16-hour preparation cycle and a delivery schedule that starts as early as 2 a.m.

The Economics of a Family Institution

The stakes of this transition extend beyond the loss of a local leader. For small-to-mid-sized family businesses, the “succession gap” is a frequent point of economic failure. Many such enterprises struggle to maintain the quality and cultural identity that built their reputation when the original visionaries step aside. Mark, however, was vocal about his preparation for this shift, having mentored his son, Jeff, since Jeff was 13 years old.

In a 2025 interview, Mark expressed a rare level of contentment regarding the state of the business, noting that he had largely stepped back from operations to let the next generation lead. He predicted then that Jeff would likely make the company more profitable than he ever had, describing his son as a “go-getter” with a work ethic suited for the modern landscape of the food industry.

CEO Spotlight: Mark Ostlund of Sandy's Donuts

This transition is now being tested under the weight of sudden loss. Beyond the emotional toll on the Ostlund family—which includes Mark’s son Jesse and daughter Jenna—there is the practical reality of maintaining a three-location operation that serves a wide geographic footprint across North Dakota and Minnesota. The community’s outpouring of support reflects the role the shop plays as a social hub, with residents sharing memories that span decades of morning routines and special occasions.

The funeral service for Mark Ostlund is scheduled for Friday, Nov. 13, at 2 p.m. at the Salem Evangelical Free Church in Moorhead, with visitation beginning at 1 p.m. In a final nod to the shop’s identity, the service will be followed by coffee and doughnuts.

As the business moves forward, it does so with the foundation Mark helped secure. He leaves behind a company that grew from a single cast-iron pan in Tioga to a regional staple, a trajectory that suggests the strength of a business is often found in the stability of its leadership transition.
