Pastor Roger grew up in Orlando, Florida. He met his wife Dianne while attending Dordt University. Together they have been blessed with 4 children (and their spouses) and 8 grandchildren. Upon completing seminary and being ordained in 1986, he served CRC congregations in Medicine Hat, Alberta; (Calvin CRC) Rock Valley, IA and Luverne MN. In July of 2021, he completed training to became an STM (Specialized Transitional Minister) and has served as interim pastor at CRC’s in (Bethel) Waupun, WI; Bangor, ME; and Appleton, WI.

In September, 2025, Pastor Roger and Dianne relocated to Pella to be an interim
on the staff here at Calvary CRC. He’s still working on learning names! He enjoys
preaching, teaching and providing pastoral care. He counts it a joy to share the
Good News of God’s Word; that there’s hope for all in Christ. He and Dianne enjoy road trips, visiting family, drinking coffee, reading and going for walks..

Pastor Sheldon (emeritus) has served as Calvary’s Minister of Congregational Life and Outreach since 1999.  Yes, he knows that’s before many of you were born!   He grew up in South Dakota, and graduated from Dordt University and Calvin Seminary. In 2022 he retired and now spends most of his time doing pastoral care, particularly among those who have a bit more life experience.  He considers it a privilege to walk with our members through times of joy and loss, and enjoys finding ways to share God’s love with those in the Pella community. 

Pastor Sheldon has two daughters, Regina, who works at Wildwood Hills Ranch, and Ramona, who still lives at home because of her special needs. Ramona’s unbridled joy and enthusiasm is a special gift that she shares with our Calvary family.  Pastor Sheldon enjoys fishing and traveling, especially to the mountains.

Joy serves as the Office Administrator, helping to keep the flow of communication open and managing week to week logistics for the church.  Studying Graphic Design at Dordt College and abroad, Joy met her husband overseas in Australia, lived in South Korea, and has tried her hand at many unique jobs. Growing up at Calvary, Joy has found herself called back to serve the church at different stages of her life, finally settling in Pella with her husband and family in 2015. 

Through her personal experiences at Calvary, she sees a loving family made up of a patchwork of called individuals; the mom who’s concerned if you’re ok, the big brother making sure you tow the line, the cool older sister who you always want to hang out with, and the wise old grandpa that’s always there for advice or words of wisdom. 

An integral part of keeping our church property maintained is the faithful work of the custodians. The Kelderman family has been the custodians at Calvary for over 30 years. Currently three generations of this family serve in various roles to maintain our church properties in a manner that provides a neat, clean appearance and an inviting atmosphere for everyone.

Christy has volunteered as Church Historian/Archivist since September of 1997. She keeps all church membership records up to date as well as keeping a record of all historical events at Calvary. She creates a historical record book about Calvary for each year which contains pictures of staff, the council, special events, special bulletin/newsletters and pictures of Calvary members. She is also in charge of keeping all items in the archive room filed properly. She is married to Jim. They are both active in Calvary Broadcast/Media Ministry.
