Creating a brighter tomorrow for individuals with primary immunodeficiency.
MORE THAN JUST AN INFECTION
Primary Immunodeficiency (PI) disorders often hide in plain sight. For many, what seems like a common cold or a routine infection is a sign of something far more serious—a lifelong challenge the immune system isn’t equipped to handle. At the Yellow Bear Foundation, we exist to change the trajectory of those stories. Through greater awareness, earlier diagnoses, and critical funding for research, we’re building a future where PI is understood, treated, and no longer overlooked.

RARE DISEASE ISN'T RARE
Primary immunodeficiency impacts so many people, and yet there is still a lot of research that needs to be done to establish better diagnostic protocols and develop treatment plans for people with PI disorders. Our purpose is to ignite the conversation and empower communities to spread awareness for PI and raise funds for life-changing research and treatment.




SPREADING THE SUNSHINE
At the Yellow Bear Foundation, we're here to shine a light when families often feel like they're in the dark. From raising awareness about PI to supporting research, hosting community events, and telling stories of individuals facing a diagnosis—we’re here to make PI visible, treatable, and talked about. Every step we take brings a little more warmth, hope, and healing to those who need it most.
