Donations are tax-deductible and go directly toward improving access to treatment, resources, and support for children with MCAS in underserved communities.
Mast cells are meant to fire at something. In MCAS they fire anyway, and because they sit in tissue all over the body, the reactions arrive everywhere at once.
That is what makes it so easy to miss. Hives belong to one specialist and stomach pain to another. Brain fog and the kind of exhaustion sleep does not fix often belong to nobody. Each doctor sees a fragment, so patients get handed along, and the years add up before someone reads the whole set as a single condition.
There is no cure. Treatment means antihistamines, mast cell stabilisers, and learning your own triggers the slow way, since no two patients share the same list.
Understand MCAS →We raise money for research and get care packages onto hospital wards. Most of the work is plainer than that, though: putting MCAS into language a family can use in the week they first hear the word.

Our numbers
We fund MCAS research through community fundraisers and youth-run detailing events, and we send cards and care packages to patients on hospital wards around the world, because a condition nobody has heard of is a lonely one to have.
It began in 2021 with one high schooler detailing cars in Illinois. It runs now on students in more than twenty countries, most of whom have never met each other. Some of them have MCAS. Most do not, and came because someone they know spent years being told there was nothing wrong.
