Thank you everyone for your support and donations!!!!!

SC4ARC is participating in Coastside Gives, a giving challenge to raise money and awareness for local nonprofits.

Our "Power Hour" is May 4th from 1pm - 2pm. Please consider giving during this time so we can get the highest number of "unique" donors. Your donation will also be matched by a generous donor!
