Team O’Brien began in 2016 during Brennan O’Brien’s battle with adrenocortical carcinoma. For his 30th birthday Brennan asked his family and friends to support him in a Cycle for Survival ride to raise money for rare cancer research. He wanted to help others also on a devasting rare cancer journey and was the featured patient speaker at that event on February 26, 2016. Brennan recognized that rare cancer research is drastically underfunded.

Team O’Brien Foundation, Inc., was formed to continue supporting those on the front lines of rare cancer research and evolving treatments. Brennan believed deeply in Dr. Gary Hammer and his team. Dr Hammer was incredibly supportive to Brennan and his family. Today, our mission is to advance rare cancer research and improve outcomes for patients worldwide.

Our premier annual fundraiser is the Team O’Brien Golf Outing. All donations directly benefit the Adrenal Neoplasia Program within the Rogel Cancer Center, steered by Gary Hammer, M.D, and leading the world-wide research of adrenocortical carcinoma. Together we are helping drive progress and bring hope and cures to families affected by rare cancers.
