WASHINGTON, DC, December 6, 2022 – The Childhood Arthritis and Rheumatology Research Alliance, also known as CARRA, announced the appointment of Mathieu Nelessen as Chief Executive Officer, effective January 9, 2023.

The CARRA Board of Directors unanimously approved the recommendation of Mr. Nelessen by a CARRA CEO search task force, which led a three-month nationwide search.

Mr. Nelessen assumes the CARRA CEO post following a decade of leadership positions with the American Red Cross, rising from New Jersey Regional CEO through a succession of increased responsibilities with the American Red Cross national organization, recently as Vice President of Business Strategy and Planning, Biomedical Services. He previously led the American Diabetes Association’s New Jersey Chapter as its Executive Director.

“We welcome Mathieu to the country’s foremost network of pediatric rheumatologists,” said CARRA President Robert Colbert, MD, PhD. “CARRA intently focuses on our mission to turn the corner on childhood rheumatic diseases. Mathieu’s clear leadership skills and outstanding track record with prominent, science-based health advocacy non-profits bodes well for pursuing CARRA’s vision to advance treatments toward cures for juvenile idiopathic arthritis and related diseases,” Dr. Colbert added.

“I’m honored and thrilled to take up the helm of CARRA,” said Mr. Nelessen. “With the organization’s solid strategic plan already in place to support the research that the nation’s leading pediatric rheumatologists and their programs generate, it’s an exciting time. I feel the hope and promise of better days ahead for children and adolescents and their families,” Mr. Nelessen said.

Mr. Nelessen will replace CARRA’s Interim CEO Larry Hausner, who was contracted for 2022 to guide CARRA through its transition of all the organization’s operations from an association management company to independent management, a process that concludes in December.
