The Groen brothers grew up on a farm in Minnesota with thirteen additional siblings. From this they learned the value of commitment, community and family. Fenton and his wife Shirley moved to New Hampshire in 1977 to raise their eight children. In 2000 Fenton decided to start a homebuilding company with his two sons Dave and Joe. The company started out very modestly – their first job was installing a single air conditioner! 


Since their founding, Groen has strived to utilize energy efficient resources, lower costs and demonstrate that new construction from Groen Construction is a long-term solution. The new name reflects the commitment to their customers and expertise in driving the innovations needed to shape the future of commercial and residential construction.

Groen Construction Historical Timeline

Our modest entry into the industry and each project since has been influenced by family values - The Groen family has built a reputation for integrity, quality, respect and unwavering commitment to our clients. 



We strive to do what is right even when no one is watching and to always be honest,

dependable, responsible and fair with our employees, customers, contractors, and

suppliers. We hold ourselves accountable to God and to His standards given in the Bible.


We take pride in building exceptional quality into each construction project and in providing high value to our customers. And we always stand behind what we build.


We value each person’s unique gifts; appreciate each person’s contribution; and respect each person’s intrinsic value, understanding that we are each created in the image of God.


We focus on actively listening to and understanding the wants and needs of our customers. We build what you want and need, and we make your building experience a positive one.


We work together as employees, customers, contractors, and suppliers, using the

contributions of each to produce optimal and lasting results.

"Groen made the whole process easy so we could run our busy wholesale operation while the office construction took place. It has been close to ten years since the construction and our new office still fills all our needs. We will always recommend Groen Construction."


Ken Michael, Millican Nurseries Inc.

It was so nice dealing with a family operation during construction.  The attention to detail in the finish work is superb, and we constantly get compliments.  Even though we are on a busy street, the ICF construction means that there is almost no road noise inside, and our heating bills have been very reasonable."
