Shannon & Tonya,


We want to thank you for the tremendous job you did for us with our new home. This goes well beyond the unique design and careful construction process which you Shannon, guided seamlessly and professionally through a challenging time in our world. It includes the enormous and creative assistance that you Tonya, brought to the process of taking that design, refining it and arranging decor that enhanced everything, turning a great house into our special home. 


Every building project meets challenges along the way and you guys met and addresses each circumstance in a way that made our experience with the project so enjoyable. After completion, you’ve stayed engaged, every bit as much as when the project was underway, to assure that follow up items were addresses and completed to our, and your satisfaction. We are so impressed by this commitment. Thank you!


We’ll enjoy our beautiful and comfortable new home for years to come and we owe that privilege to the commitment you both demonstrated, from start to finish.


Thanks to each of you, and to NRG Homes. We not only built a wonderful new home, we built an equally important friendship.
