Voice of Christian Doctor's Media Training


Dr. David Stevens, author of Jesus, MD, Beyond Medicine and co-author of Leadership Proverbs, serves as Chief Executive Officer of the Christian Medical & Dental Associations (CMDA), a national organization of Christian healthcare professionals that seeks to change hearts in healthcare. As untold thousands of people who have heard him preach could attest, Dave Stevens is a gifted storyteller and a powerful Christian communicator with a passion for evangelism and a deep understanding and respect for the integrity of God’s Word.

As the son of an itinerant Methodist evangelist who, like John Wesley himself, truly saw the world as his parish, Dave comes by his speaking skills honestly. He’s honed his talent over the years in an incredible variety of settings. Whether he’s recruiting tribal leaders to provide volunteer support for a community health initiative in rural Kenya, preaching at American mega-church missions conferences, testifying before a panel of Washington politicians on Capitol Hill, or challenging an auditorium full of doctors to better integrate their personal faith with their professional practice, Dave knows how to hook and hold an audience. While always unashamedly Christian in terms of his convictions and values, Dave can hold his own in non-Christian and even decidedly anti-Christian settings. His ability to clearly communicate difficult spiritual truths, foundational biblical values, scientific facts and thorny bioethical issues gives him an authoritative voice to speak out frequently on behalf of the American Christian healthcare community. It’s also enabled him to initiate and lead a program that has trained thousands of Christian healthcare professionals how to use, but not abuse, their authority to be and offer spiritual light and salt in a world where so many patients need more than physical healing.
As a leading, trusted spokesman for Christian healthcare professionals, Dr. Stevens has conducted thousands of media interviews, including JAMA, USA Today, Newsweek, NBC's Today Show, NBC Nightly News, BBC-World Television, CNN and National Public Radio. He has also appeared on FOX Family Channel, PAX-Television, Tech TV, The Odyssey Channel, America's Health Network and many other national outlets. Prior to authoring his first book, he wrote a regular health column for the Promise Keepers' New Man magazine and served on the editorial board of Christian Single magazine.

Dr. Stevens is also heard as host of the CMDA Healthwise Public Service Announcements, which address general health and bioethical issues. CMDA members hear him as the host of the popular Christian Doctor’s Digest audio magazine, which has featured national leaders such as Kay Arthur, John Stonestree, Jim Cymbala, Newt Gingrich and Luis Lugo.

Dr. Stevens holds degrees from Asbury College and the University of Louisville School of Medicine and is board certified in family practice. He earned a master’s degree in bioethics from Trinity International University in 2002 and serves on the board of Asbury University. He currently serves as a fellow of the Biotechnology Policy Council of the Wilberforce Forum. Dr. Stevens and his wife Jody have a son, Jason, and two daughters, Jessica and Stacy, and five grandchildren.


Mike Chupp, MD, was born in Frankfort, Indiana and grew up in the suburbs of Indianapolis, Indiana. He graduated Summa Cum Laude with a pre-medical degree in chemistry from Taylor University in 1984, and then graduated as an AOA scholar with an MD degree from Indiana University in 1988. He completed a five-year general surgery residency at Methodist Hospital in 1993. Since then, he has been a member of the Surgical Department of Southwestern Medical Clinic (a large Christian multi-specialty group) and Lakeland Regional Health System in St. Joseph, Michigan. Mike has been married to Pam for 25 years and they have four children: Steven, Melody, Kayla and Ashley. They recently completed 20 years of service as career missionaries with World Gospel Mission, serving at Tenwek Mission Hospital in Kenya.

Dr. Chupp testifies that he is an example of how life and ministry don’t always turn out the way you expect. In his words, “During my years of ministry at Tenwek Hospital, my surgical emphasis wasn’t on general surgery, but it was primarily on orthopedic trauma surgery. My work at the hospital also wasn’t what I had planned or expected over most of my career (80 to 90 percent of my time was devoted to administration and leadership for the hospital and WGM Kenya mission leadership). But God’s gifting and preparation and character development in our lives was not wasted. In 2015, Dr. David Stevens and Dr. Gene Rudd asked me to consider joining the executive leadership team at CMDA. Dr. Stevens was the Medical Director at Tenwek when I volunteered there as a medical student in 1988. He had a big influence on me to choose a career as a missionary surgeon there beginning in 1996. It is a great honor and exciting privilege to join the organization that has had the longest and deepest impact on my professional life as a Christian physician. Paul told Timothy in 2 Timothy 1:6-7 to ‘…fan into flame the gift of God, which is in you…’ (NIV 2011). We believe God asked us to join the CMDA team at this time to fan into flame God’s call and the Spirit’s gifts to healthcare professionals who love Jesus first…until He comes back.”
