The Fortney Family · Three Generations of Builders
We build things.
Including a place to land.
Our Story
A construction family bought a resort.
Hillside has been Lake Madison's gathering place for decades. The current chapter began in 2024, when Luke Fortney and his son Ben took the keys from Jeff and Debbie Luther — the family who had reimagined the property starting in 2015 (and built everything you'll recognize on the patio: the Steakhouse, the BluCabana, the BluMana party boat, the marina).
Luke isn't a hospitality guy by training. He runs Empire Building Construction in Sioux Falls — the company his dad Ercell founded in 1983, that Luke worked his way up through (summer crews → mechanic → project supervisor → operations manager → VP), and bought outright in 2019. Empire has put up schools, performance centers, townhomes, and commercial steel across four states.
That matters for a resort more than it sounds. A builder-owner walks every dock and knows whether it's level. Reads a leaking cabin roof in five seconds. Doesn't accept "that's how it's always been" as an answer for a kitchen vent. The first thing Luke and Ben did when they bought the place was a punch-list walk — every cabin, every roof, every line of plumbing. The hidden infrastructure of a resort that guests never see is the thing that breaks a weekend. We don't let it break.
Ben runs day-to-day. He's the one you'll meet at the marina, the one who actually built the fleet booking system. Teasha Torpy handles operations and events. The kitchen team and front of house include staff who have been here through multiple ownerships — they know what works.
We didn't reinvent Hillside when we bought it. We inherited a going concern from the Luthers and Mageos that we genuinely admire. Our job is to keep the docks tight, the kitchen running, the cabins clean, and the music playing. And to make sure the weekend you spend here is the one you'll talk about.
The Family Business
Empire Building Construction · Founded 1983
The Fortneys have been building things in the upper Midwest for over forty years. Schools, performance centers, townhomes, commercial steel. Hillside is the latest chapter of a long construction story — and the first one that's also a place to stay the weekend.
How We Got Here
Forty years of building. Eleven years of Hillside. One running timeline.
- 1983
Empire Building Construction is founded
Ercell Fortney founds Empire in Sioux Falls. Over four decades the company grows into a 70-person general contractor building schools, performance centers, townhomes, and commercial steel across South Dakota, Minnesota, Iowa, and Nebraska.
- 2014
Luke joins Empire's leadership
After working summer crews as a teen, mechanic shifts after tech school, and project supervisor years, Luke Fortney becomes Vice President + General Manager. Five years later he buys the company from his dad.
- 2015
The Luthers reimagine Hillside
Jeff and Debbie Luther buy The Hillside on Lake Madison and modernize it with their son-in-law Nefu Mageo as GM. The Steakhouse opens upstairs, BluCabana opens dockside, and the BluMana party boat joins the marina in 2020. The current Hillside footprint takes shape.
- 2019
Luke buys Empire from his dad
Generational handoff. Luke takes ownership of Empire after coming up through every seat in the company. Empire is now a third-generation South Dakota builder.
- 2024
The Fortneys take the keys at Hillside
Luke and his son Ben buy the resort from the Luthers. The first thing a builder-owner does at a multi-venue property: walk every dock, every cabin, every kitchen line. The cabins stay tight, the docks stay level, the kitchen keeps showing up.
- 2025
Honoring Emmy on the water
Luke renames the public-cruise boat the Emmy 1 in memory of Emmy Gorman, a 13-year-old who died in a Lake Madison jet-ski hit-and-run. The Hillside hosts boater-safety training each summer.

Yesi and the rest of the Hillside crew — the people you actually meet on a weekend. Some have been here through multiple ownerships. They are the Hillside.
What We Stand For
The four things we won't compromise on.
Builders, not operators
We come from construction. We know what a tight cabin, a level dock, and a kitchen that doesn't break down feel like. That standard runs through everything we touch at Hillside.
Two lakes, one address
We sit between Long Lake's no-wake calm and Lake Madison's full-throttle open water. Pick your mood; the dock works either way.
Food and dock, same family
The Steakhouse upstairs. Hemingway's downstairs. BluCabana on the patio. The Sea Store across the street. Same family runs all of it. Same standards.
Open year-round
Summer is loud. Fall is golf and steaks. Winter is ice fishing, snowmobile-friendly cabins, and Friday-night fireplace dinners. Spring is when the loons come back.
