Our History
Mount Horeb, Wisconsin native Jeff Grundahl founded JG Development in 1990, primarily focusing on residential new construction and remodeling. He expanded the firm’s work into commercial construction on his own, as well as through the purchase of three existing commercial firms in 2008, 2011 and 2024. In 2015, Jeff and his co-owner and wife, Mary Grundahl, launched two new residential construction brands, Brio Design Homes and Vive Home Transformations, and established JG Development as a family of companies providing a complete construction solution.
About Our Parent Company
JG Development loves to build. We build homes, we build commercial structures, we build places of worship, and we build more. But what we really love to build is intangible: trust and long-lasting relationships.
We love what we do, and we want you—our customer—to love what we do for you.
To that end, we’re a quality-focused organization. And to deliver quality, we offer the specific knowledge, experience and expertise your project needs through our five divisions:
Brio Design Homes: Our new home building division

National Construction: Our original commercial division with broad capabilities currently focused on housing, multi-tenant buildings, light manufacturing & recreation
