More details about the JWBIII Foundation…
This year we will be raising funds for the JWBIII Foundation, a foundation created by Coach James and his family in honor of his dad!

The JWBrine III Foundation is a registered 501(c)3 charitable organization. Our mission of keeping Jim’s spirit of giving alive by giving to others in their time of need is our main purpose. We have also given to other charitable organizations and have distributed many scholarships to high school seniors in the pursuit of a higher education. The generosity of individuals and groups will contribute directly to these causes. Please visit our website, follow us on Instagram at jwbrineiiifoundation and like us on our Facebook page during the year to find out about upcoming events and to keep informed on how this foundation, with the generous donations of our supporters, like you, are helping to aid others as they face difficult times. We thank you and think of each of you as we are able to make donations to others. Jim would be happy to know that his generous and kind spirit lives on through the JWBrine III Foundation.

All money raised will allow for the foundation to continue on in supporting families, communities, students, and organizations. Over the years we have donated to families who find themselves in difficult situations, to students through college scholarships, to other non profit organizations near and dear to our mission, to cancer research at Mass General Hospital, and so much more.

We cannot thank each of you enough for your support over the years. Your love inspires us every day and we find so much joy in knowing Jim’s love and spirit lives on in each of you.
