Cornerstone Graduate Supply, Inc. (DBA Homeschool Diploma.com) is a family-owned and operated business located in Southern Wisconsin. Our goal 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 keep our prices fair and to deal with our customers, vendors and employees with integrity.

Established in 2002, we are a professional graduation supply company, serving thousands of homeschooling families and support groups each year, as well as nearly 500 "brick and mortar" schools. We enjoy developing products to meet the specific needs of our customers and 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. Our dedicated staff set a new record in the spring of 2009 -- 100% of orders were shipped on time according to the schedule of production time listed on our site. 

Our customer's privacy and data storage security is a very high priority for us.  We have achieved our goal of becoming 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.
