The Illinois Catholic Medical Association is a professional association of Catholic doctors in Illinois, united by faith, and interested in the ethical practice of medicine. At present there are four regional guilds in Illinois: Chicago, Joliet, Peoria, and Springfield. All Catholic physicians, dentists, and medical students are welcome to join.

As Catholic Physicians of the United States and Canada, we come together in the Catholic Medical Association in order to grow in the spirit of Christ in our personal and professional lives, to bring His Spirit to all that is touched by our science and art, and to assist the Vicar of Christ, the Bishops, and the whole Christian community with leadership, especially with the particular knowledge, skill, and experience we have as Christian Physicians.
