It is with great sadness that we announce the passing of Byron Syphrett.

Byron was one of the “founding fathers” on the C1S construction team, and he played a major role in making our company what it is today. His teammates loved him and his clients loved him. One client even named him “Employee of the Month” for his dedication and commitment to the project. Byron was one in a million, and we are all better for knowing him.
