Who We Are

Welcome to the LARS Collaborative

Welcome to the LARS Collaborative, a dedicated community of healthcare providers, researchers, and individuals living with LARS (Low Anterior Resection Syndrome). Our diverse team is united by a shared mission: to address the challenges posed by LARS and its associated sequelae.

Our Mission Together, We Can Impact LARS: Empowering Patients, Educating Communities, and Improving Lives

We are a global collective of experts and leaders in LARS, united by the shared goal of highlighting the importance of addressing this condition and its significant impact on quality of life. Through our collaboration, we aim to:

Educate and Empower

Provide both patients and clinicians with the knowledge, tools, and resources they need to navigate the challenges of LARS.

Engage and Share Insights

Foster a community where open dialogue and shared experiences lead to new insights and better care practices.

Contribute to Meaningful Change

Work on impactful research that drives improvements in the lives of those living with LARS.

Our mission is to create a supportive network for patients, caregivers, and healthcare professionals, where they can find education, resources, and community. No one should face the journey through LARS alone—Together, we can make a difference. Every patient has a voice, and together, we can amplify it to create lasting impact.
