Tyson Olheiser, Senior Pastor


My wife (Rebekah) and I both grew up in Oregon and got married a couple years after high school.  After completing my undergraduate studies at Oregon State, we moved to Champaign-Urbana in order for me to attend graduate school at the University of Illinois in 2001.  The next year, we began attending Calvary Baptist Church.  At the time, we both claimed to be saved and began a Bible study to learn more.  Within a couple months of studying the Bible, I began to realize that I was not born again.  In early 2003, I heard a sermon that helped me to see my sin, my guilt, and my need.  I immediately repented and put my faith in Christ and His death, burial, and resurrection.  My wife soon came to the same realization and got saved.

As we continued to attend Calvary and were mentored by a godly couple, we began to get involved in ministry.  I began teaching part time in the school and working with the teenagers.  Later, I started teaching an adult sunday school class and became heavily involved in evangelism.  As time went on, I began to feel God working on me about surrendering to full time Christian service.  In 2010, the Lord’s call became clear to me and others, resulting in me beginning as the assistant pastor that fall.

During my 10 years as an assistant, the Lord opened the door to a variety of new ministries.  I was ordained in the summer of 2019 and then called to be the senior pastor at Calvary Baptist in the Summer of 2020.  I marvel at how the Lord has led us to this point.  Praise God!


Ministry Experience/Education

As a youth pastor at Calvary, I had the privilege of being involved in a variety of teen ministries.  The majority of my time was spent as a full time teacher and basketball coach.  My wife and I led separate teen classes for the boys and girls in an attempt to have a more specific ministry focus for each group.  I was also blessed with the opportunity to teach Sunday School, disciple new believers, and participate in several modes of evangelism.  With regards to education, my path was unconventional, but I know the Lord has a reason in everything.  I received a Bachelors in Physics at Oregon State and a Masters and PhD in Physics at the University of Illinois at Urbana-Champaign.  I’ve also received a Masters of Theology degree from Baptist College of America.  


My Family

My wife and I have been blessed with 10 children:  Austen, Henry, Aaron, Peter, Elizabeth, Ty, Cecilia, Bennett, Cameron, and Abraham.  Though having a big family can get pretty chaotic at times, we truly view each one of them as a blessing from the Lord.
