We are a group of family and friends of patients with Primary Immunodeficiencies. We are an independent, non-profit organization formed under the umbrella of the Jeffrey Modell Foundation. We work in cooperation with the Immune Deficiency Foundation and other local groups in the New England area.

For clinical advice, we depend upon the skills of the talented staff of Dr. Raif Geha, Chief of the Immunology Division at Children's Hospital.

Our mission is straightforward: educate each other and the public about PI, support each other, and raise money to support research into future cures.
