Share a slice of pie and spend time with a sister this Pi Day! The date March 14 marks the beginning of the mathematical constant pi (3.141529…), and in the same spirit, ADPi celebrates on this day the life-long friendships that remain the constant core of our sisterhood. It’s sharing the little moments, often over a treat, that make sisterhood so sweet! And this year, ADPi is making it easy and delicious to reconnect with sisters.
The Sorority is partnering with Southern Baked Pie, a pie-shipping business owned by a fellow NPC sister. Featured in the Oprah Magazine, Southern Living, Garden & Gun, and on the Today Show, these pies bring family recipes and Southern charm right to your table. In the lead up to Pi Day, Alpha Delta Pi members can order from a collection of sweet and savory pies (curated just for us!) at the discounted price of $31.14 for regular and $39.95 for gluten free pies. Select the pies and delivery date you want or ship one as a gift with a message to a sister you miss!
Choose from Chicken Pot Pie, Spinach and Mushroom Quiche, French Coconut Custard, Buttermilk, and Chocolate Chess or invite a group to spend Pi Day with you and try all five. If you discover friend-favorites, these pies stay delicious for up to 6 months in the freezer, so you can stock up. As you make memories and hopefully start some traditions, take pictures of you and your sisters to share on social media or send to photos@alphadeltapi.com.
Share in the fun of Pi Day and honor our letters by spending some quality Pi-time with those who wear them.
For those local to Atlanta, celebrate Pi Day by registering to attend the Memorial Headquarters and newly renovated History Center open house here.

Who collects pop tabs? ADPi sisters do! Throughout August 2026 we need everyone to collect pop tabs for Ronald McDonald House. In celebration of our 175th anniversary, we are challenging our sisterhood to collect 1,750,000 pop tabs. Does that sound overwhelming? Well, 1,750,000 pop tabs only fills 455-gallon bags! And this total is for our entire sisterhood. If you want to get started early and be an over achiever, feel free. Get your campus, community, or place of work involved. There will be graphics to decorate your collection containers. If your local Ronald McDonald House does not participate in pop tab collection, donate to another house or take your pop tabs to a recycle center and redeem them for cash to donate.
