Merry Christmas!!

Thank you to all who put together a great Hartford's Hometown Christmas, Hartford SD. We put together a great float with the help of my wife, kids, Ashley, Keke, Jesus and Logan! Special thanks to the Nielson family for walking with us and handing out candy.

We would like to wish all families a Merry Christmas and Happy New Year!

Quick update for our new construction! Over the last two months we have had Siemonsma electric, Darrin’s plumbing, new prairie insulation, Irvine Construction LLC, Hartford Building Center, MasterBrand Cabinets, and Carpet One Of Sioux Falls get this house moving along great! All of the guys that help us bring plans to life are the absolute best to work with! Soon we will be tackling the trim! After we clean up the floors can shine again and we can hope to get the Nielson family moved in soon!

Here are some pictures of our progress on Joey and Kelsey’s after a month. Hopefully this week we get the house enclosed and can start working towards getting her sealed up and ready to get finished up this winter! Thank you Hartford Building Center for getting us everything so far!

Monday kicked off an exciting start to building Joey and Kelsey’s dream home on their farm! We are excited to take on this awesome project and I can’t wait to see this home take shape! We will see how the family’s and the surrounding change over the coming months!
