 Our Pastors


Pastor Ralph, Lead Pastor

Rev. Ralph Van Oostveen B.Th
     Born in Stratford and raised on a farm in Listowel, I graduated from Listowel District Secondary School in 1984. Following graduation I auditioned and was accepted to join a ministry group based out of Colorado Springs Colorado for one year. During that year as I travelled throughout the USA and Canada, I sensed a clear call from God to train for full-time ministry. I graduated from New Brunswick Bible Institute in 1989 and immediately entered the pastorate.
     I met my future wife Kim, at Bible College and in 1990 we married. We have three children. Our son Michael was born in 1992, our daughter Alyssa was born in 1997 and our youngest, Ava was born in 2006.
     I was a pastor at the Palmerston Missionary Church(1989-93), then Elgin Missionary Church in Stratford(1993-2002). In the fall of 2002, with the blessing of the congregation and leadership at Elgin and our denomination, I led a group of people here in Mitchell to launch what we know and love as Upper Thames Missionary Church.
     Having grown up in Perth County, I have a real fondness for Mitchell and the region of West Perth, and I look forward to many more years of fruitful ministry.


Pastor Nate, Pastor of Ministries

     I grew up in Stratford, ON and now live in Mitchell with my wonderful wife, Alli, our daughter Casey, and son, Andrew. I’ve been serving at Upper Thames Missionary Church since 2014.
     In 2011 I received my Associate of Arts in Music from Briercrest College and Seminary in Caronport, SK. After taking a short break I returned to Briercrest and received my Bachelor of Arts in Humanities in 2015. Studying the disciplines of literature, philosophy and history in conjunction with biblical studies and theology has given me a great appreciation for what God has done and continued to do today in the world around us. 
     In 2020 I have begun working toward my Master’s of Theological Studies at Wycliffe College.
