Community Involvement

Whittlesey has a rich history of contributing to our local communities, both as individuals and as a firm. We encourage our staff, at all levels, to become actively involved with the nonprofit organizations in the areas where we live and work. Our partners and managers take on leadership roles, volunteering their time and sharing their talents with organizations across the region. In line with our commitment to our local communities, we established the Whittlesey Fund, a charitable fund managed by the Hartford Foundation for Public Giving. Moreover, thanks to the generosity of our employees, Whittlesey proudly supports the United Way and the Greater Hartford Arts Council annually.

In addition to individual efforts, we organize an annual Community Day for our company. It represents one of the most exciting days of the year for Whittlesey, as we close our offices and our team engages in hands-on volunteer service at several nonprofits.
