**★★★★★ — Teton Steel, Inc., July 2017**

> Rex is always a great guy to deal with. Projects are always looking sharp, job sites are clean! He is always looking for new materials and designs. Meticulous attention to details! Highly recommend Timberline.

**★★★★★ — Stan and Sharon Dardis, June 2017**

> We decided to do a major home remodel in 2013, tripling the square footage. Timberline Associates met all our expectations and more. We wanted a rustic mountain look, using stone, timber, cedar and recycled barn wood. It was a complicated design that evolved with the help of an excellent contractor. Rex Doronbus gave us that "Rex Magic" we were looking for. We finished on time and are proud of the quality and workmanship of our home.
