Last week we celebrated the most delicious math joke of the year—with donuts instead of pie. Why? Because like π, donuts are perfectly round… and infinitely enjoyable! Pi Day, at ADMA Biologics, is more than a celebration of the mathematical constant, it’s another reason to celebrate, honor, and advocate for our PI (Primary Immunodeficiency) patients. Take a look at a few moments from this year’s celebration! 🍩🍩🍩🍩🍩
