Welcome to Home Base!

The Thiesen family, left to right: Nicole, Ron, Jessica, Joshua, Charissa, and Bonny

Our current Home Base guests are Ron and Bonny Thiesen. As career missionaries, they have spent 30 years serving in both Hungary and India, primarily working with Discipleship Training Schools. For the past eight years, they have been serving as missionaries with YWAM (Youth With A Mission) as teachers at the International Christian School of Budapest (ICSB). Ron teaches high school science and coaches, while Bonny teaches a global awareness course to seniors. The school serves missionary families from 19 different mission agencies, enabling parents to stay in the field. Three of their four children are attending college this year—Wheaton and Cedarville. Their daughter Charissa is a sophomore at Concordia Academy while they are on home stay.

While not Impact partners, the Thiesen’s do have a Calvary connection! Bonny was a college roommate of Sue Zeller, our Event Coordinator at Calvary Church. When Thiesen’s were looking for a home stay option, Sue told Bonny about Home Base. We hope the Thiesen’s enjoy their stay at Home Base!

The purpose of Home Base is to provide a welcoming and restful place for Calvary’s Impact candidates and partners (and others serving in ministry around the world) to recharge while on home assignment.

The home has been completely refurbished inside and out by contractors and volunteer work teams from Calvary. Home Base is fully-furnished and has all new appliances in the kitchen and laundry room and a new gas fireplace in the living room. There are two bedrooms and a nook area upstairs, and one bedroom on the main level.

Our desire, first and foremost, is that Home Base will be a peaceful place for rest and recovery. Beyond that, we hope it will serve as a Home Base for our partners and friends to visit with family, friends, and support team members while at home.
