Joseph P. Brennan

Chief Executive Officer

Joe Brennan is the Avalon Action Alliance’s first CEO, one carefully chosen to guide its next phase: from proof-of-concept launch to scaling as a sustainable national leader.

Joe is passionate about solving the nation’s mental health and mild traumatic brain injury system, failing many of our country’s military and first responders. He has seen how these can cascade into generational impacts on families and communities.


He brings over three decades of relevant healthcare business, Naval service, and personal concussion experience to Avalon. As a CEO, founder, and growth driver in the medical and pharmaceutical arena, he launched and scaled healthcare companies, gathered clinical and programmatic data to influence standards of care, and forged strong funding models across philanthropic, government, and private sectors.

Joe became the CEO of Avalon in October 2022. Previously, he served as CEO of Innovative Trauma Care and neoSurgical and held senior management positions with Sanofi (formerly Genzyme) and 3M KCI (formerly Acelity), among others. At Innovative Trauma Care, he drove the process to gain U.S. government approval for an innovative hemorrhage control device. At Sanofi, he grew the biosurgical division’s commercial sales from $10 million to over $100 million and supervised multiple diverse teams throughout his 17-year tenure. At 3M KCI, he achieved year-to-year commercial growth for skin substitute and wound care product lines.


Joe is a graduate of the United States Naval Academy. He served in Operation Desert Storm as a Division Officer on the USS Frederick and worked with the Chief of Naval Operations in the Foreign Liaison Office. He has an MBA from the Goizueta Business School at Emory University.


He is a former college football player and a family man. He resides in Atlanta and is married with six kids and an animal menagerie which currently includes two dogs, two cats, fish, frogs, and a tortoise.
