Marybeth Gilliam is a metastatic breast cancer survivor, healthcare strategist, and founder of Outperform Cancer, a non-profit podcast and website dedicated to translating peer-reviewed research into actionable anti-cancer strategies for patients. First diagnosed with stage 0 ER+, HER2+ breast cancer in 2007 and later with metastatic disease in 2020, she combined conventional treatment with evidence-based lifestyle and healing strategies – achieving a complete pathological response and remaining cancer-free for more than five years.

Marybeth brings over 30 years of leadership experience across healthcare, biotechnology, and emerging technologies, including serving as Chief Operating Officer at Greensea IQ and leading her own consultancy serving clients such as The Hospital of Silicon Valley, El Camino Health, where she served as the lead researcher on an Agency for Healthcare Research and Quality (AHRQ) grant evaluating the role of technology in patient engagement.

She is an active patient advocate, currently serving on the Dartmouth Health’s CREATE Advisory Committee, University of Vermont Cancer Center’s Protocol Review and Monitoring Committee, and Theresa’s Research Foundation’s MARP Committee where she co-authored a publication in npj Breast Cancer highlighting the importance of collaborative partnerships between advocates and researchers. She is also a member of the Metastatic Breast Cancer Alliance.

Using storytelling skills developed during her time as Director of Marketing for George Lucas’s Educational Foundation, her latest initiative “Cancer Hates Exercise” is designed to draw attention to the largely unknown fact that exercise reduces the risk of cancer recurrence by 30-50% while raising money to support Dr. Kathryn Schmitz’s goal to make exercise oncology standard of care for all cancer patients by 2029.

Through her professional work, volunteer leadership, and personal story, Marybeth is committed to bridging the gap between science and patient communities to empower people facing cancer with knowledge, hope, and strategies to improve outcomes.
