🎆🇺🇸 HAPPY 250TH, AMERICA! 🇺🇸🎆
Cornerstone would like to wish everyone the happiest 4th of July as we celebrate America's 250 YEARS! What a moment. What a milestone. What a country!
For two and a half centuries, this nation has been built one neighbor at a time showing up for each other, standing together, never backing down. That spirit built America, and that same spirit is alive right here in our community RIGHT NOW.
So today, let's celebrate big! Fire up the grill, gather the family, watch the sky light up and let's remember why we do this. Because stronger neighbors make stronger neighborhoods. Stronger neighborhoods make a stronger community. And a stronger community is how America will endure for another 250 years.
🔥 SHARE this post if you're proud to be part of a community that shows up for each other! Let's spread the spirit and build something stronger — together. 🔥
HAPPY 4TH OF JULY! 🎆🇺🇸

We are Community strong!

Next generation of Future Leaders!

Sherman Park Grocery Store needs our help, neighbors! The grocer on Fond du Lac Avenue at Sherman Boulevard is at risk of going out of business. It opened four years ago selling fresh fruits and vegetables and affordable groceries, but no alcohol or to***co. It remains true to that vision today. The owners are also members of the community, as well as loyal and active supporters of SPCA. Now it's up to us to show them our appreciation by visiting their store and spending some money.
