Our Staff

Here at GMC we are blessed with an amazing staff to keep the day to day operations rolling right along while focusing on giving God all the glory.


Marv Claassen, Associate Pastor

Marvin Claassen has been married to his wife, Sue, for over 50 years.  Together they ministered for 44 years in Missionary Churches in Illinois, Michigan, Ohio, and Nebraska before coming to Groveland in 2012.  They have three sons, Chris, Tim, and David, and six grandchildren.  Their focus is on ministering to people in their homes, in hospitals, and in nursing facilities.  They want to help people in their walk with the Savior.  Marvin received his education at Fort Wayne Bible College and Bethel College.


Cindy Wallen, Office Administrator

Cindy Wallen serves as GMC’s Office Administrator. She enjoys living in the country near Groveland with her husband Michael. They have three young adult children who are expanding the family by adding spouses. One of her favorite verses is 3rd John 4, “I have no greater joy than to hear that my children are walking in the truth!”  She attended Asbury College and earned her B.A. degree from Greenville College. After teaching several years, they moved to the Groveland area and Cindy was involved in assisting home-schooled families. About 15 years ago when Michael became disabled with Multiple Sclerosis, Cindy was blessed to step into the GMC’s office full time to serve Jesus and the people of Groveland Missionary Church.
