For Shane Obertein, building has been his passion since his first job in construction at the young age of 12 years old. He attended vocational school through high school and was greatly influenced by his grandparents who ran a local lumber yard. He established his own carpentry business when he was 24 and developed a love for working with clients and making them happy. It was through his many successful years in the carpentry trade that he realized he wanted to do more to serve people’s needs. He decided to shift his focus from carpentry to custom home building.

He leads our project management and is responsible for the overall building process, eliminating issues before they arise, and consistently finds ways to build better homes. As a builder, his main goal is providing the best experience for clients, going through the building process, delegating tasks and organizing the many sub-contractors on the jobsite. If, on the rare occasion, you can’t find Shane at the jobsite, he is guaranteed to be at the local coffee shop or the health club.”

Her love for helping people find homes, create a space that is their own, along with knowing the design essentials and trends, was met with her desire to work in the custom home building industry.
