Bryan and Mary are U.S.-trained physicians and both dual-dual-board-certified in the specialities of Family Medicine and Psychiatry. They enjoy providing direct patient-care for both medical and psychiatric needs as well as being available to other medical providers through telemedicine services, collaborative-care, distance support, and academic/teaching programs.

They have spent several years in Cameroon, West Africa, at Mbingo and Banso Hospitals, and are venturing into the world of "Member Care" - caring for the mental health needs of missionaries and global workers - with Tumaini Counseling Centres in Nairobi and Kampala. They are hopeful to maintain a connection to Cameroon and return physically in some capacity when the political unrest settles down.

Their medical interests and experience include:
- collaborative care (model of med-psych integration)
- integration of physical, medical, and spiritual
- member care, care for global workers and ex-patriates
- spirituality, religion, ethics, and medicine
- global health in general, with an emphasis on global mental health and W.H.O.'s mhGAP curriculum

When in the U.S., they call Columbus Ohio home and work at The Ohio State University Wexner Medical Center.

Elizabeth Grace Cairns, their daughter, was "made" in Cameroon, "assembled" in Kenya and Uganda, and joined the outside world in 2019.
