Pastoral Staff:


Rev. Rebecca Jordan Heys, Minister of Worship and Pastoral Care

I rejoice in serving as the Minister of Worship and Pastoral Care at Calvin Church: preaching and planning worship, providing spiritual care and counsel, leading the staff, and encouraging and equipping this congregation in their growth as disciples of Jesus Christ and in their mission in our community.  I served as the Minister of Discipleship at Calvin Church from 2011-2017 and then transitioned to my current role.

I was raised in Fremont, Michigan and attended Calvin College and Princeton Theological Seminary.  I was ordained as a Minister of the Word in the Christian Reformed Church in 2009 when I served at Church of the Servant in Grand Rapids.  I am married to Kyle Heys, who works at Calvin College.  We have two children: Jubilee and Lazarus.

Other Staff:


Kenneth Bos, Director of Music, Organist

It has been a pleasure for me to be a part of the music staff at Calvin Church since September 1996. I began as organist and then acquired some additional duties, eventually becoming Director of Music. My position includes playing the organ, conducting the Sanctuary Choir, keeping track of the music budget, and scheduling and overseeing all of the fine musical activities that go on at Calvin Church. In addition to my work at Calvin Church I am a full-time faculty member in the Music Department at Grand Rapids Community College. My wonderful wife, Fay, and I have been married for over 40 years. We are blessed to have three married daughters (and three pretty good sons-in-law) and five adorable grandchildren.

Kim Fredricks, Church Office

I began working at Calvin church in 2012.  I am grateful to have been able to serve elsewhere as a church secretary since 1999.  Serving God by serving others, I find I receive more than I am ever able to give.

I am a true Michigander, having lived, been educated, and worked in this beautiful state all my life.

My daughter, Megan, her husband, Bryan, live in Indianapolis, IN; my daughter, Kelly, and her husband, Josh, live in Seattle, WA; and my son, Brad, lives in Woodbourne, NY. I have two furry children still living at home, Pippin & Millie, who are Papillons, two grand-kitties; Milo & Toby, and a grandson, Ethan and granddaughter, Eliza.

I enjoy reading, knitting, cooking, playing games, and gardening.
