The Timberline Difference
Timberline Builders has refined the process of custom home building from design to construction. The Timberline Difference has everything to do with people. We build with excellence, but more importantly, we care about personal growth in ourselves, our employees, and in the lives of the clients we get to serve. We have a rich history and strive to continue to build our team to exemplify integrity, relationship, thoroughness and fairness.
Timberline started in 1973 when Ralph Greslin, a draftsman who worked for a local lumberyard, decided the office environment and his tiny cubicle were too constraining for his taste. With a small pile of hand tools and a six-foot ladder, he began a venture to start his own construction company. The first job he had lined out was a small kitchen remodel, which ended up falling through shortly after giving notice that he would be leaving his draftsman position. However, he wasn't deterred from moving forward with the dream he knew he needed to pursue. He embraced the process of growth by facing many challenges along the way and learning the value of flexibility and tenacity. Ralph and his wife, Carleen, owned and operated Timberline Builders for 39 years, laying a strong foundation of honesty, financial responsibility, and the value of people before profit.
Meet the Team
Michael & Jenny Greslin, Owners
Always eager to help his dad, Ralph’s son, Michael, would spend his summers working with the crew throughout junior high and high school. He worked as a laborer, a carpenter, and a foreman until 2008 when he became the General Manager. Michael and his wife, Jenny, purchased Timberline Builders in December of 2012. Currently, Michael oversees all aspects of the business. Although his primary focus is on keeping the vision out in front of the team, he still loves the hands-on aspect of construction work and it’s not unusual to find him sitting in an excavator preparing a new job site. Michael and Jenny live in Spearfish with their three boys…and it appears as though the love for building has passed down to another generation!

Our Core Values
We believe in doing what’s right and are actively focused on the development of our character. We make a conscious choice to do what we say we will do and authentically are who we present ourselves to be. Our goal is to lead with consistency in our actions, methods, and outcomes.
We recognize that the building process involves entering into a partnership that requires mutual trust. We value this process and take the necessary time to build that trust with our clients through open communication, honesty, and collaboration. We place the same value on the relationships we have with our many sub-contractors, material suppliers, and company employees. At the end of the day, we really are in the people business.
We are attentive to accuracy and detail and are committed to completion without negligence or omissions. We hold ourselves to consistent standards that can be seen in the soundness of our building practices and inside of the way we communicate.
From the initial cost proposal to requested changes that arise during the building process, we treat our clients with respect and fairness. We know the value of our craft as well as the value of your investment and make every effort to ensure you are getting the best your money can buy.
