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, Globe Santa, CitySprouts, and the Arlington Food Bank, 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!

For the past several years, Siena has replaced sending a traditional holiday card with a digital card accompanied by a donation made on behalf of our amazing clients. Each year Siena picks an organization doing great things for their communities.

In 2016 we’re working with Razia’s Ray of Hope Foundation. Razia Jan is working to improve the lives of women and children in Afghanistan as the country rebuilds after years of upheaval. The foundation believes 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 cause.
