Tim is a lifelong student of apologetics and loves nothing more than a good conversation on faith and truth. He is the chapter director of Ratio Christi at Grand Valley State University in Allendale, Michigan (his hometown). He has spoken on dozens of apologetic topics at various universities, high schools, churches, and non-profit ministries. He has a BA in Worldviews and Apologetics from Boyce College. His subjects of expertise are the problem of evil and practical apologetics. He has a passion for equipping the church to be effective in reaching out to their community. Tim, his wife Alexandra, and children MaryKate and Oliver attend Allendale Baptist Church where Tim also works as an administrator. Anyone who meets Tim easily remembers him as the tallest Filipino they’ve ever met.


Tim is a recovering Pharisee. He grew up in a Christian home where he was faithfully taught the Bible, theology, and how to live the Christian life. Growing up he thought he was the model Christian as he carefully observed “the law” by being a good kid and reading his Bible every day. After reading a book on leadership which challenges the reader to reflect upon his own soul, Tim began to pay attention to the nature of his heart and found it to be evil. It wasn’t long before he realized that he had been trusting his outward actions for salvation and that he needed to instead have faith in Jesus Christ.

Immediately after becoming a believer Tim became quite zealous for evangelism. He shared the gospel with anyone he could force into a conversation. However, the conversations never seemed to go well. Everyone had a seemingly good reason not to believe in Jesus. Before long, Tim entered a dark period of doubt. One day, driving home from work, he heard Ravi Zacharias on the radio for the first time and was fascinated. After listening to and reading everything “Ravi” he could get his hands on, he was introduced to the world of apologetics. Tim decided to make apologetics ministry his life’s pursuit and hasn’t turned back since.
