Executive Committee

President

Dr. John Shin graduated from Loma Linda University School of Medicine then completed his internal medicine residency and hematology/oncology fellowship at Mayo Clinic in Rochester, MN. He also completed an advanced fellowship in cancer immunotherapy at the National Cancer Institute in Bethesda, MD. Dr. Shin currently works as a medical oncologist at Loma Linda University and has a burden to share Christ with cancer patients.

Dr. Shin is grateful to have been mentored by the AMEN organization throughout his time in training and seeks to inspire the next generation of healthcare professionals to dedicate their careers to Christ. As president, Dr. Shin’s vision for AMEN is that it will serve as a catalyst for all people to engage in effective medical ministry for the purpose of spreading the gospel message.

His wife Elisa is a dentist by training, and they are blessed with three children: Sophia, Charis, and Kyle.

Secretary

Dr. Kianna Simmons graduated from the University of Pennsylvania’s School of Dental Medicine in 2007. During her time there she developed a keen interest in the connection of oral health and general medicine and continued her studies at the University of Pennsylvania’s oral medicine residency program. After completing a year of clinical training she returned to Bermuda where she entered private practice.
Dr. Kianna has been involved in numerous community initiatives and is actively involved in a number of local community and professional organizations.
In 2012, Dr. Kianna married Mr. Devaun “Sammy” DeGraff, and in 2015 were blessed with their son Kenan. Dr. Kianna enjoys spending time with her family, and in the fall of 2015 they traveled to their first AMEN conference in Hilton Head, South Carolina. It was there that Dr. Kianna was inspired and recommitted herself and her practice to God and began seeing her profession as a ministry, and not just a practice. Since that time she has incorporated praying with patients, more thorough comprehensive medical exams and assessments, and advises patients holistically on care for not only their teeth, but their health overall. By providing spiritual insight and guidance and support to patients on their journeys for change she enjoys serving her patients as well as the community. Her goal is to not only physically cure oral disease, but ultimately inspire and reflect Christ to every patient and introduce them to Him, one consult at a time.

Treasurer

Dr. Brian Schwartz is an Interventional and Structural Heart Cardiologist and serves as Medical Director of the Heart and Vascular Service Line at Kettering Health in Dayton, Ohio.

Having been personally touched by the power of the gospel, Dr. Schwartz longed to make his medical work a healing ministry. His association with AMEN has helped him integrate prayer and Christian spirituality into his practice in a more intentional and natural way.

Dr. Schwartz served as AMEN president for 5 years and editor of the Medical Evangelist (AMEN’s Journal) for 10 years.

He and his wife, Lyndi, also a physician, have a passion for the gospel and ministry.

Dr. Guthrie sees AMEN as a catalyst to further facilitate the bringing together of the everlasting gospel of Revelation 14:6–12 and the Adventist health message. He firmly believes that medical missionary evangelism will open hearts in preparation for and in conjunction with the outpouring of God’s Spirit in the final days of earth’s history. Dr. Guthrie, his wife, Patti, and their four children have been involved for years in ministry in their local church and abroad.

Dr. Seheult is currently an Associate Clinical Professor of Medicine at the University of California, Riverside School of Medicine, and an Assistant Clinical Professor of Medicine at the School of Medicine and Allied Health at Loma Linda University.
