Once we find a cure for celiac disease, it won’t be due to the work of one individual. It will be because we are all working together to further the mission of Celiac Disease Foundation. We are proud of the work we do. Meet some of the extraordinary individuals who work tirelessly to keep Celiac Disease Foundation the number one resource for celiac disease.

Marilyn G. GellerMarilyn Grunzweig Geller, Chief Executive Officer

Marilyn is Chief Executive Officer for Celiac Disease Foundation (CDF), the nation’s leading voluntary health organization for celiac disease and gluten sensitivity. For 14 years, Marilyn’s son suffered with debilitating symptoms despite seeking help from innumerable health professionals. A chance blood draw revealed celiac disease was the cause of his suffering. From that day forward, Marilyn, a longtime healthcare executive, became active in celiac disease advocacy, joining the CDF National Board of Directors. In 2012, Marilyn succeeded Founder Elaine Monarch as Chief Executive Officer.

Marilyn has focused CDF on two important initiatives: FDA gluten-free labeling regulations and a national awareness campaign to increase the shockingly low rate of celiac disease diagnosis. A strong believer in the power of technology, she continues to develop online tools to empower patients to seek diagnosis and treatment of celiac disease. Under her guidance CDF joined the Community Engaged Network for All (CENA), a patient empowerment network of the Patient Centered Outcomes Institute (PCORI), and is one of the first organizations to participate in the American Autoimmune Related Diseases Association (AARDA) autoimmune research network. In 2014 she hosted the autoimmune disease roundtable at the Milken Institute Partnering for Cures conference. In 2015 served on the FDA GREAT3 Steering Committee and was named an inaugural winner of the Alpha Chi Omega Real. Strong. Women. of Distinction Award.

Because of her in-depth knowledge of the issues surrounding celiac disease, Marilyn has become a primary spokesperson on the gluten-free labeling issue. She has been featured nationally on the Hallmark Channel’s Home and Family Show, internationally on television networks in Europe and the Middle East, and in numerous newspapers and magazines, including USA Today, National Geographic and Gluten-Free Living.

Marilyn brings more than 20 years of management experience in healthcare and IT operations. A former Los Angeles County and UCLA hospital administrator and RAND Corporation researcher, she is a co-founder of Medversant Technologies, where she was responsible for the company’s strategic direction and is the lead inventor of the company’s patented technologies. Marilyn’s nonprofit experience includes board positions with the Olive View-UCLA Foundation, UCLA Health Services Alumni Association and Alpha Chi Omega.

Becoming CDF’s Chief Executive Officer marks a return to her roots in public health advocacy. Selected as a Los Angeles County Department of Health Services Fellow, Marilyn received her MSPH degree from the UCLA School of Public Health and her undergraduate degree from UCLA.
