We are thrilled to share that Will Shappley will be the Honorary Corporate Grand Marshal for Walk 2026.
Will is Vice President of Structured Products, Americas at BP. Alongside his professional work, Will is deeply committed to supporting Breakthrough T1D, a mission that is profoundly personal to him and his family. His daughter, Mary Ellis, was diagnosed with type 1 diabetes at the age of five. Since that day, type 1 diabetes has become part of the Shappley family’s daily reality. Through this experience, Will has seen firsthand that type 1 diabetes is not something that goes away—it is a lifelong condition that requires relentless attention and support. The Shappley family became involved with Breakthrough T1D shortly after Mary Ellis’s diagnosis and has remained deeply engaged ever since participating in annual walks, building “Team Mary Ellis,” and helping raise awareness, funding, and community support. What began as a way to cope and connect has evolved into a sustained commitment to accelerate research, improve care, and ultimately find a cure.
