Keeping It Local

If supporting local businesses is essential to you, you’re not alone. 60% of consumers report that they prefer to buy from family-owned businesses, according to Family Business Magazine.  Besides the economic advantages of retaining more dollars within the community as compared to purchasing from a national brand, other causes such as American entrepreneurship, providing better-paying jobs, helping local causes and even the prioritization of environmental sustainability is advanced right in your backyard.
