I have worked with them during an outbreak in Peru, specifically looking at how people could get tested for Hepatitis A/B and Zoonosis (dengue). They were very efficient at putting together a study that helped answer our research questions quickly and efficiently without any issues or problems from us. It was not as thorough as we requested but they did what we needed by helping design and run studies with minimal resources. The cost was reasonable too! Not great, but ok for this use case…
