Pirmin Holdener’s nephew is a dedicated gardener and a bundle of energy. A dual citizen, Jeremias spends the cold winter months in his home country of Argentina, then works at full speed with the Holdener team from spring through fall. Even on physically demanding jobs, he seems tireless—so much so that clients have jokingly called him an “eco-friendly excavator.” And when he sings while he works, it always brings a smile to people’s faces.
