01 / About
Long-term thinking, applied to real businesses.
Holsum began as a Holsum bread franchisee. Over four generations it has become a family office and operating holding company. Andrew became its CEO at 30 and has led it for more than a decade, working with its board and family shareholders on governance, capital and strategy.
Before Holsum, he spent seven years at Symantec in software engineering and program management, focused on enterprise security. He still runs the business like an engineer: clear systems, honest data, steady execution.
02 / Leadership
One enterprise, three disciplines.
Agriculture
Holsum Dairies
Wisconsin dairies milking 8,000 cows. Holsum Central, now in development, is built around a 120-stall rotary parlor, tied for the largest in Wisconsin, sized for about 5,000 milking cows.
Renewable Energy
Renewable Natural Gas
Since 2019, turning dairy biogas into pipeline-quality renewable natural gas.
03 / Approach
How I lead.
Stewardship
Family capital is held for people who aren't at the table yet.
Ownership
Owners fix problems; they don't wait to be assigned them.
Integrity
Tell shareholders and teams the truth, especially when the numbers are hard.
Continuous improvement
See people's potential and help them grow into it.
“Leave things better than you found them.”
04 / Perspective
What carries a family enterprise across generations.
Family enterprises rarely falter for lack of capital. They falter when leadership, ownership and trust don't survive the handoff between generations. A few lessons from leading a fourth-generation company:
Succession is a process, not an event.
The families that do it well start preparing the next generation of owners long before anyone needs to step aside.
Governance has to grow with the family.
Clear boards, voting rules and family councils keep decisions sound as the number of shareholders grows.
Write down what the capital is for.
A clear mandate settles arguments before they start and makes risk and performance easier to judge.
Communicate more than feels necessary.
Shareholders who hear from the company regularly, in every generation, stay aligned when it matters.
