The Heritage Team

Dr. Joel Eugene Yeager hails from Chambersburg, Pennsylvania. The youngest of four, he always felt inclined toward books and music. After graduating from Anchor Christian School in 1986, he spent five years teaching there. During that time, he wrestled with what felt like a “call” to medicine. Chorister assignments at church services and a summer Bible conference brought him into contact with Dr. Bob Webb, a Mennonite family physician from Indiana. Spending time in Dr. Webb’s office convinced Dr. Joel of his calling to family medicine.

In the fall of 1991, he embarked on undergraduate studies at Shippensburg University. His calling to marriage and medicine intersected when he met LuAnne. After a spring courtship and fall proposal, they were married on January 2, 1993. In 1996, he graduated from James Madison University. An innate interest in the art of medicine combined with his mentoring by Dr. Webb led the newlyweds to Denver in the summer of 1996, where Dr. Joel did a one-year Master of Arts in Biblical Counseling at Colorado Christian University, a program developed by Dr. Larry Crabb and Dr. Dan Allender.

Dr. Joel’s time in Colorado brought him peace with the concept of moving overseas for five years to begin a program at Cambridge Overseas Medical Training Programme/Kigezi International School of Medicine. A whirlwind journey of studying medicine with LuAnne, both didactically and clinically, ensued. After graduating in May 2002, Dr. Joel spent 11 months as a counselor at Life Counseling in Lancaster County before completing a three-year family and community medicine residency at Penn State Hershey/Good Samaritan Hospital in the fall of 2006. With the help of a management team, he developed StoneRidge Family Medicine, serving with Dr. LuAnne from spring 2007 to early 2011. A providential series of events led them to their current practice at Heritage Family Health, PC. Their practice provides the basis for a model outlined in Dr. Joel’s 2018 book, Transforming Healthcare Together: A Model for Restoring the Covenant of Trust.

Dr. Joel comments often about how he loves what he does. His natural way of putting patients at ease in the office has caused confusion on occasion. Patients wonder whether he is the doctor or the pastor in the room! God blessed Dr. Joel with a heart dedicated to Truth—both in seeking and speaking it out. His passions outside of medicine include choral music, landscape photography, vehicle detailing, and Christian apologetics.

Dr. LuAnne Derstine Yeager lived in the Franconia area of Pennsylvania until her family moved to Harrisonburg, Virginia when she was nine. In 1988, she graduated from Berea Christian School, and while an aptitude test showed that she excelled in science, she chose instead to tend chickens on her father’s farm for two years until beginning a teaching career at Berea Christian School in 1990 that lasted for five years. 

Dr. LuAnne and Dr. Joel first met in the summer of 1989 at a summer course for teachers. They began dating in early spring of 1992. By July 4th of that year, Dr. LuAnne settled on marrying Dr. Joel if he should propose…which he did. They married in January 1993. In 1996, the couple transitioned to the foothills of the Rockies near Denver, Colorado, where Dr. LuAnne completed a first grade Learning to Read primer published by Christian Light Publications.

Nearly four years into marriage, they moved once more, this time to the United Kingdom where Dr. Joel began an international medical school program. Feeling totally clueless as to what she would do with her time, Dr. LuAnne felt shocked when, about a week into classes, the medical school dean invited her to “try the hat on” —in other words, join Dr. Joel in classes without an undergraduate degree! (This stunning story is related in more detail in Dr. Joel’s book, Transforming Healthcare Together.) Dr. LuAnne’s unanticipated entry into medical school is a God-story that completely re-directed the course of her life!

Thus began a five-year partnership of studying medicine together across the globe. Because no one from Kigezi International School of Medicine had ever applied for residency in Pennsylvania, the State Board of Medicine undertook a six-month review of the school before granting Dr. LuAnne a training license. Finally, in the summer of 2002, she began her three-year residency in family and community medicine at Penn State Hershey/Good Samaritan Hospital. From there, Dr. LuAnne practiced at Fredericksburg Community Health Center until she and Dr. Joel opened StoneRidge Family Medicine in Myerstown, where they practiced from 2007 to 2011 before moving to their current location at Heritage Family Health.

Outside of medicine, Dr. LuAnne enjoys choral singing, puzzle-making, memory work, quietness and solitude, and cooking and baking—where she tweaks a recipe at least six times before it is perfect!

David (Dave) grew up in Lancaster County with one brother 2 years younger than him to the day. He always felt a calling to medicine and decided to attend nursing school, graduating from Lancaster General Hospital School of Nursing in 1994. He began work at Penn State Hershey Medical Center in the Medical Intermediate Care Unit and the Medical ICU. He went back to school and became a pre-hospital RN through HACC and started to volunteer on an ambulance in Harrisburg. In 1998, he became a flight nurse with the Life Lion Air Medical Program. During this time, he felt a calling to go back to school and graduate from Millersville University in 2021 as a Family Nurse Practitioner. After 23 years of service with Life Lion, Dave is now ready to shift his focus to preventive health maintenance and management of complex disease processes in a rural setting.
