Dr. Felicia McCreary, MD

CHSC Board Member & Patient Safety Officer

For as long as I can remember, I have had a deep passion for the downtrodden, the marginalized, and the intentionally victimized. As a child, I would tend to injured animals – I even wanted to be a veterinarian.  However, constant sneezing and shortness of breath while around animals dissuaded me from becoming a vet.  Instead, as I got older, I focused my energies on helping people.  In high school, I partnered with the “Big brothers, Big Sisters” program – helping children find connection in a world where they often went unnoticed.  I continued my passion for others by volunteering with the YWCA as a battered women victims advocate – educating women in abusive relationships and empowering them to break the abuse cycle.  While in undergrad at Creighton University, I founded a chapter of Habitat for Humanity; with focused effort, we were able to build a home within only 2 years!!   As I moved on to medical education at Creighton, I was first exposed to mission work during a month long OB rotation in the Dominican Republic.  It was a powerful experience to see how much even a little help could aid those without regular access to medical care.  My desire to participate in mission trips remained strong throughout my time as an anesthesiology resident at the University of Arizona.  This vision was once again realized as I have now visited the Philippines to aid the people of Tagbilaran City, on the island of Bohol.  In the last couple of years, I have had the privilege of partnering with the Christian Health Service Corps.  I was able to help the people of Dessalines, Haiti by providing anesthetics for many patients there.   Through these varied experiences, I have seen the influence that medicine can have on peoples’ lives and the opportunity it presents to speak into their lives and share the gospel with them.  I am extremely pleased at the consideration the Christian Health Service Board of Directors has extended to me; I am excited to continue to partner with CHSC.  It will  be a fun adventure to see what God has in store for this new stage in health care mission work.

Dr. Joel McCreary, DO

CHSC Board Member

Born at the end of his father’s family practice residency, Joel saw firsthand his father’s joy in serving patients and passion for his work. From the time he was in the seventh grade, Joel planned to go to medical school.  After attending Greenville College in southern Illinois, he headed to medical school in Arizona.  At Midwestern University, he discovered his enthusiasm for anesthesiology despite his original plans to follow his father’s footsteps into family medicine. Although he was concerned that he would not be able to utilize the skills of anesthesiology in a mission field setting, a mentor showed him the fantastic potential to help drastically change people’s lives through surgical missions. Three surgical mission trips to the Philippines and three to Haiti (with Christian Health Service Corps) have only bolstered his passion for people in places in need of surgical care.  He embraces the philosophy of partnering with local healthcare providers as much as possible to build long-term sustainable healthcare solutions.  He has seen the influence that medicine can have on peoples’ lives and the opportunity it presents to speak into their lives and share the gospel with them.
