Eleventh annual convening will unite patients, survivors, researchers, clinicians, industry leaders, and lawmakers to strengthen advocacy and advance public health protections
NEW YORK, NY | Apr 1 — The Peggy Lillis Foundation (PLF), the nation’s leading nonprofit dedicated to C. diff education and advocacy, today announced its 2026 National C. diff Summit and Lobby Day, taking place Monday, April 13, 2026, in our nation’s capitol.
Since the organization’s founding, PLF has trained and supported C. diff survivors, caregivers, and family members to become effective advocates, public speakers, and peer supporters. Over the past decade, the Foundation has hosted ten National C. diff Summits and seven Lobby Days, building a national movement focused on care, community, and empowerment.
The 2026 Summit will bring together C. diff survivors, caregivers, clinicians, researchers, industry partners, and policymakers for a full day of programming designed to elevate patient voices and accelerate solutions to this ongoing public health threat.
“Sixteen years after the death of my mother, Peggy, there has been progress but also setbacks. C. diff continues to cause harm, and too many patients still struggle to access timely diagnosis, effective treatment, and informed care,” said Christian John Lillis, co-founder and CEO of the Peggy Lillis Foundation. “The Summit and Lobby Day bring together the people closest to this issue to push for solutions that improve outcomes and save lives. When lived experience, science, and policy come together, we accelerate progress.”
