We are a nonprofit stool bank, 

expanding safe access to fecal transplants

and catalyzing research on the human microbiome.


What we do

We work with clinicians to make Fecal Microbiota Transplantation (FMT) easier, safer, and more widely available. We do so by providing hospitals with screened, frozen material ready for clinical use. This service eliminates the time, staff, protocols, and facilities needed to screen and prepare material from new donors for each treatment.

Why we're here

We founded OpenBiome after watching someone close to us suffer through 18 months of C. difficile and 7 rounds of vancomycin before finally receiving a successful, life-changing fecal transplant. The remarkable effectiveness of this treatment for C. diff and the great lengths required to receive it convinced us that we needed to help expand access.
