Siena Construction is an active and proud member in the communities in which we work, live, and play.

In addition to our affiliation with the Cambridge Historical Society, Cambridge Chamber of Commerce, Cambridge Science Festival, and City Sprouts, our incredible employees volunteer their own time to a variety of projects and initiatives. Follow us on Twitter to see what we’re up to!

Siena makes an annual holiday donation on behalf of our amazing clients. Each year Siena picks an organization doing great things for their communities.

For the past several years, we’ve chosen to support Razia’s Ray of Hope Foundation. Founded by Razia Jan, the Ray of Hope works to improve the lives of women and children in Afghanistan as the country rebuilds after years of upheaval. The foundation founded the first all-girls school in rural Afghanistan, believing that “education is key to positive, peaceful change for current and future generations.” We’re very proud to have the opportunity to provide support to this life-changing cause.
