The only organization worth going to for help in the Porphyria's. You can get answers to questions that are difficult to find elsewhere. The USPA has helped me get a lot of my life back by recommending sources to go to and people that understand the disease. You will be hard pressed to find any other organization that has the understanding of the Porphyria's and is kind enough to walk you through any personal struggles with the disease you might have. Highly recommended!!!
