About Our Company

Cornerstone Graduate Supply, Inc. (DBA Homeschool Diploma.com) is a family-owned and operated business located in Southern Wisconsin.


We are a professional graduation supply company which serves thousands of homeschooling families and support groups each year, as well as approximately 500 "brick and mortar" schools. We've been in business since 2002, and we enjoy developing products to meet the specific needs of smaller schools. We strive to ship every order on time, correctly filled.


With few exceptions (such as class rings or engraved items) all of the products on our site go out within 5 business days. Most ship in 1 - 3 days even during the busiest time of year. We employ just over 20 people, many of them seasonal, and we are privileged to be located in the small town of Milton, Wisconsin where there is a strong work ethic and great sense of community.

Our customer's privacy and data storage security is a very high priority for us. We are certified as "compliant" with the payment card industry (PCI) standards through an independent company called Security Metrics, and are scanned and reviewed quarterly. This means that the data stored in our office, as well as the security of our web site, meet the high level of the PCI Security Standards Council. We do not outsource our customer service or our advertising.

The personal goal of our family's business is to serve homeschooling families and small Christian schools with products and service that will honor our Lord, Jesus Christ. We want to encourage and enable others to give glory to Him for what He has allowed them to accomplish through Christian education. We are blessed by the loyal following of customers who tell their friends and fellow educators about our business!

We strive to offer the highest quality items at fair prices and to deal with our customers, vendors and employees with integrity. We welcome your comments or suggestions about our products and our web site.
