It’s Women in Construction Week!

The focus of Women in Construction (WIC) Week is to highlight women as a viable component of the construction industry. WIC Week also provides an occasion for the National Association of Women in Construction’s thousands of members across the country to raise awareness of the opportunities available for women in the construction industry and to emphasize the growing role of women in the industry.

We’re proud to recognize all of the women in construction and all of the women on the Siwek Lumber team!

Happy Women in Construction Week and Happy International Women’s Day!
