During her initial medical treatments—all of which failed—Joan realized the world of ITP was a lonely fight. Answers were limited and resources for strength practically non-existent. Her persistence and self-advocacy led to remission, but Joan wasn’t done. Because of her commitment to help others, a website was created for people from all over the world to share their trials and successes of living with ITP. From this creation of community, PDSA was brought to life just five years later.
PDSA is now the exclusive ITP resource in North America with a voice resonating around the world. Each day, we serve the global community of patients, practitioners, caregivers, advocates and key disease stakeholders, promoting their needs through worldwide unification.

Whether you are newly diagnosed or caring for a loved one with ITP or another platelet disorder, PDSA is your resource for empowerment through education, advocacy, research and support.
