NRG Homes was started by Eric Ward of WS Construction located in Sioux Falls, South Dakota. WS Construction is a construction management firm that specializes in Commercial, Agricultural and Industrial projects. Eric started NRG Homes to focus on the "greener side" of residential construction.

NRG = Energy. Energy Efficiency is the key to building a great home.

Shannon Grismer came aboard as a partner with NRG Homes in March of 2018. He joined Eric with over twenty years of home building experience including the construction of single family homes, twin homes and villas. His vast knowledge of the industry has greatly increased the exposure for NRG Homes. In the last year since Shannon has joined NRG, we have won back to back Parade of Homes awards for the categories we were entered in.

To make a great situation even more amazing, Shannon's wife Tonya Grismer, joined NRG Homes as the full time Interior Designer in March 2019. It can be very overwhelming to build a house AND decide what all should go in it! All of those decisions can be made a lot easier with the help of a designer to talk through all of the details from lighting options, tile, and carpet to sink fixtures and drawer handles! This is a great feature to have when building a home that most people have to pay extra for. Tonya's style is impeccable! She and Shannon can make your wants, needs and dreams a reality!
