We envision a world where C. diff is rare, treatable and survivable.

Peggy Lillis Foundation is building a nationwide C. diff (Clostridioides difficile) awareness movement by educating the public, empowering advocates, and shaping policy.

About Peggy

Margaret Mary “Peggy” Lillis (nee Daly) was born into a large, Irish-Catholic, working class family in Brooklyn, New York. She married in 1973 and had two sons, Christian and Liam. She separated from her husband in 1979, beginning her life as single mother.

Despite these challenges, in 1987 Peggy earned an Associates Degree in Education and began working for the New York City Board of Education as a paraprofessional. She also waited tables on weekends to supplement her family’s income.

Over the next 15 years, Peggy successfully raised her two sons, while continuing to work as a para and a waitress, and earning a Bachelors Degree in Psychology from Brooklyn College.

A vocal advocate for students in the public education system, Peggy eventually became a Kindergarten teacher and taught for the last six years of her life in Flatbush, while working toward a Master’s Degree at Touro Colege. In 2009, she finally became a homeowner, purchasing a house with her son in Marine Park, Brooklyn. At the time of her death, Peggy was teaching at PS 198, caring for her elderly mother, and planning to spend her retirement between her home in Brooklyn and her long-time partner’s house in Maui.

Bruce Hirsch, MD

About Bruce

Bruce Hirsch, MD is a graduate of Cornell University Medical College. His infectious disease practice focuses on optimizing the complete health of a person. Illness is not just biology – we are often impacted in every aspect of our lives. The irony of infection resulting from antibiotics manifesting as Clostridioides difficile colitis has been one professional focus. Together with Gerard Honig, Dr Hirsch developed and described the effectiveness of transfer of fecally derived bacteria by oral capsules and was honored with an Innovators Award by the Peggy Lillis Foundation – the largest lay-person advocacy group for C. diff in the country. Dr Hirsch recently published research describing persistent enhanced morbidity and mortality for those hospitalized with C. diff throughout the 180 days follow up measured. The phenomenon of C. diff reveals our relationships with the microbial life that sustains us, with the well-intentioned but flawed health practices that sometimes hurt us and with our understanding that health and well being are precious and connected with the well being of others.

Scientific Advisory Council

The Scientific Advisory Council (SAC) is a group of researchers and healthcare providers who work in close collaboration with PLF on an array of projects, including:

Peggy Lillis Foundation’s Advocates Council

Peggy Lillis Foundation’s Advocates Council is a nationwide network of individuals whose lives have been impacted by a Clostridium difficile (C. diff) infection, whether directly or through a loved one. Comprised of volunteer community leaders, the Council is the nucleus for our national movement to raise C. diff awareness by educating the public, empowering advocates, and shaping policy.

Supported by PLF, Advocates engage in a wide range of activities to educate the public, support and empower CDI sufferers and caregivers, lobby for CDI-related laws and regulations at the state and federal level, and help build a powerful and sustainable movement.


C. diff is preventable and treatable and not something everyone has heard of – yet. Through our work, we’ve made measurable differences in driving awareness among the public and helped shape policy through legislation. 

Peggy Lillis Foundation is grateful to all of our generous supporters.
