The Original Betterment Company

Day & Zimmermann is a family-owned company founded over a century ago. Our first work was to develop “Betterment Reports” that helped modernize American factories.

Today we’re still in the business of betterment. We specialize in construction & engineering, staffing and defense — helping leading corporations and governments make the world a better place.

Over the last century, we helped construct the Panama Canal, put men on the moon and bring the Olympics to American households. Today we’re maintaining the nation’s power infrastructure, protecting American freedoms and driving technological advancements around the world. Behind every project is our promise of relentless reliability — we do what we say, so our customers can do their best work, better.
