We Build…® Great Teams This week, the JC&A team gathered at the Squantum Yacht Club for our latest company meeting, a chance to reconnect, welcome some awesome new faces, celebrate well-deserved promotions and have a little fun together. And because we’re celebrating 30 years of JC&A, everyone went home with some new anniversary swag! One of the most meaningful moments of the day was announcing this year’s recipient of the JC&A Memorial Scholarship Fund. Established in 2016, the scholarship supports a deserving member of the JC&A family while honoring teammates we’ve lost and carrying forward their legacy of excellence, generosity and service. Congratulations to this year’s recipient, Will Hines! As we celebrate this milestone year, it’s a reminder that our legacy has always been about our people — those who came before us, those who are building with us today and those who will carry it forward. We Build…® Our Legacy, Together.

We Build…® Communities "I truly cannot name all of they ways they have helped Bennett." Bennett first joined the Minnesota Golf team when he was going through chemotherapy.

We Build…® Our Legacy, Together. At this week’s Boston Business Journal Corporate Citizenship Summit, we were incredibly proud to learn that JC&A ranked #2 for the second year in a row for highest average volunteer hours, with 44 hours per employee. The recognition is especially meaningful as it marks our 20th consecutive year on the BBJ’s list of Massachusetts’ top corporate charitable contributors. We’ve been on the list every year since its inception and have consistently ranked among the top three companies for average volunteer hours. What an incredible honor to celebrate during our 30th anniversary year! As we mark 30 years of JC&A and 15 years of Team IMPACT, we have so much to be proud of. It all comes back to the grit, gratitude and commitment to community that have been part of JC&A from day one. Giving back is one of the ways we put that gratitude into action. Check out our attached BBJ feature, “Doing Well by Doing Good Makes an Impact,” featuring a conversation with Jay about our journey, Team IMPACT and what it means to build a legacy together. That’s doing well by doing good. It’s who we are, it’s what we’re about, and it’s what we mean when we say, We Build…® Our Legacy, Together.

We Build…® A Top Charitable Contributor! JC&A is thrilled to be recognized on the Boston Business Journal’s list of Top Charitable Contributors and receive a Corporate Citizenship Award for the 20th consecutive year! We’re proud to consistently rank in the top 3 across Massachusetts for volunteer hours, and to rank #2 this year! It’s no surprise, as philanthropy is woven into our culture. All employees are encouraged to find ways to volunteer and give back to the community. Many of our teammates roll up their sleeves to help coach youth sports, participate in various donation drives like our Christmas in July benefitting the Boston Children’s Hospital, prepare and serve meals for shelters like Father Bill’s and Rosie’s Place, deliver meals to families in need, and engage in many other rewarding experiences. The team had a wonderful time celebrating our achievement at last night’s award ceremony!

We Build…® Communities Since being matched with Harvard Men's Lacrosse through @GoTeamIMPACT, Oliver has become part of the team in every sense.
