Who Are We? We are people, just like you. The only difference is that we all suffer from Hypersensitivity Pneumonitis, or other serious lung diseases. When we were all diagnosed, none of us had ever heard of this disease. For years, we have participated in an online support group that could only reach a few hundred people worldwide. That is why we have created this site. We are hoping to reach far more people who suffer with this disease and help them gain the knowledge that we have accrued through the years.
