Dr. Dyer is an ENT surgeon with 25+ years of experience in medical missions. In 2017, he felt God calling him to step away from his private ENT practice and launch HEARTFIRE - a new type of medical mission organization designed to make the Last commandment of Jesus (“Therefore, GO, and make disciples of all nations…” Matt 28:19) the First priority. Alongside many wonderful volunteers and team members, he continues to empower, equip and accelerate mission-minded young adults, medical professionals, and other Christ followers to run into the Great Harvest. When he’s not working on HEARTFIRE projects, you’ll find him trail-running, reading, sampling his next donut, or his favorite: spending time with his extraordinary wife and two world-changing daughters.

Emily has a deep desire to see young people transformed. As a former youth pastor, she has experience in full-time ministry as well as non-profit work. She came to HEARTFIRE in 2021 and works on all things design & media-related. She is passionate about leading teams & mentoring student participants both on and off the mission field. While not at HEARTFIRE, you’ll probably find her at a coffee shop sipping on an iced latte or hanging out with her dog, Moses.

Sarah has served with HEARTFIRE since the beginning of 2022. After jumping on a trip to the Yucatán as a volunteer, she knew she wanted to serve with HEARTFIRE in a deeper capacity. Sarah has worked as an RN for 15+ years and has worked with various mission organizations throughout her career. She lives with her husband and 2 kids & loves to hike every chance she gets!
