Columbia Stone, Inc. (CSI) was started in 1988 and has since become one of the most respected dimensional stone contractors in the Western United States. We have a well established reputation based on integrity, teamwork and quality. Michael Twiss, President/CEO, refers to many of his clients and suppliers as “personal friends”. The enduring spirit of building relationships is a core value and is the foundation of the Company’s success.

Columbia Stone does not specialize in any one particular market, simply because our work is driven by the needs of our clients. This flexibility results in opportunities to provide natural stone to a variety of markets including offices, mixed-use, healthcare, education, libraries, museums, residential and government buildings.

Columbia Stone strives to deliver value to every endeavor, no matter what the project requires. Our passion and commitment thrive on complex designs, fast-track schedules, restrictive sites and arduous budgets. We provide turn-key services including conceptual pricing, value engineering, design-build, structural engineering, material selection, overseas procurement and project management. Columbia Stone, Inc. provides the planning, knowledge and support to ensure that the final product exceeds the client’s expectations.
