The work of the ICMDA is coordinated through 12 regions worldwide.

Each Regional Secretary and Regional Committee seeks to support and facilitate the work being done through national Christian medical and dental movements across their region. Much is achieved by communicating with leaders, sharing resources and connecting together those doing similar work. Conferences and training also play an important role. Four yearly regional conferences bring together Christian medical and dental, students and graduates for training and encouragement to face the challenge of following Jesus in medicine.
