Grapevine Studies is a family owned business located in central Wyoming. John and Dianna, together with their four children, have developed this unique Bible study program. 

John is an electrician and enjoys spending time with his family, hunting, shooting, and canoeing. John serves as an elder in their church and is the President of Grapevine Studies.

Dianna is a homemaker and the primary author of Grapevine Studies. In addition to being a wife and mother, she also teaches a community step aerobics class and a college Sunday School class. Dianna enjoys researching, reading, and shopping when she is not involved in the activities of Grapevine Studies.

John and Dianna have four grown children and one grandchild. All four of their children are homeschool graduates who are now working and/or attending college. The children have been a crucial part of the business serving in various capacities from administrative assistants, marketing, and advising, to working conventions.Their most important role, though, has been encouraging and praying for their parents. 

As the Wiebe family looks ahead, they pray that other families will be blessed by the materials from Grapevine Studies.
