At Siena, we believe in giving back to the communities we serve. Through our personal and professional partnerships, we can expand our understanding of what community building means: that it can encompass a global perspective, to hold empathy and support for those in need.



In addition to Siena’s affiliations with the Cambridge Historical Society and Cambridge Chamber of Commerce, our incredible employees volunteer their time to a variety of projects and initiatives.

Each holiday season, Siena picks an organization doing great things for their communities and makes a donation on behalf of our amazing clients.

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.
