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 this work we do.

Marilyn G. Geller is Chief Executive Officer for Celiac Disease Foundation. 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.

Seeking to change this all too common narrative, 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.

Founded in 1990, the Celiac Disease Foundation seeks to accelerate diagnosis, treatments, and a cure for celiac disease through strategic investments in biomedical research, patient and healthcare provider education, and public policy advocacy.

Under Marilyn’s guidance, CDF has developed:

  • The nation’s first and largest celiac disease patient registry, iCureCeliac®️.
  • The nation’s first patient-driven clinical trial and study tool, iQualifyCeliac.
  • In partnership with the Keck School of Medicine of USC and Children’s National, groundbreaking healthcare provider celiac disease education programs.
  • In partnership with Children’s National and NASPGHAN, the first national standards for 504 programs in schools to support students with celiac disease.
  • In partnership with NASPGHAN, the first online clinical decision support tool for celiac disease diagnosis.

An appointee to the PCORI Patient Engagement Advisory Panel and an inaugural winner of the Alpha Chi Omega Real. Strong. Women. Of Distinction Award, Marilyn has co-authored and presented numerous medical research papers and posters on celiac disease and its impact on patients. She has also emerged as a primary spokesperson for the patient and caregiver perspective on celiac disease, speaking at numerous domestic and international conferences and, most importantly, testifying before the House Committee on Appropriations Subcommittee on Labor, Health and Human Services, Education and Related Agencies earlier this year.

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 the lead inventor of Medversant’s patented technologies. 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.
