北美路加傳道會(LCMM)最早是由一群對醫療傳道有負擔的醫護人員在六十年代 ，從芝加哥中國城的一間教會地下室的義診開始。當時的負責人吳超厚醫師及其他幾位醫師們，不但提供免費的醫療服務，同時也帶領多人信主，並將其介紹至各教會。

七 十年代，當芬蘭差會欲將當時的二間基督教醫院-屏東和恆春-交出經營權時，吳超厚醫師及在台灣的數位醫師們，忠心的向神回應，正式成立路加傳道會。吳醫師 及多位熱心的基督徒醫療人員，並陸續回台灣支援當時人力短缺的屏東和恆春基督教醫院。一九九八年，吳超厚醫師向當時仍在南加州福樂神學院進修的李榮禮醫師 提出要求，希望能將傳福音的棒子交給年輕的一代，繼續鼓勵更多的基督徒醫護人員能將自己獻在主前，為主使用。北美路加傳道會於是在大洛杉磯地區正式成立。

LCMM, Luke Christian Medical Mission, was originally founded by a group of Christians who had a burden for medical missions. In the 60¡¦s, Dr. Stewart Wu and his associates in the medical field started a free clinic in a church basement in the Chinatown in Chicago.

Through medical care, they were able to share God's love and gospel and brought many to church and Christ. In the 70¡¦s, when Finnish mission board decided to relinquish ownership of two Taiwanese hospitals, Ping-Tung and Heng-Chun, to the native Christians, Dr. Wu and others in Taiwan faithfully responded. Thus, the organization known in Chinese as the Luke Medical Fellowship was formed. In English, the organization became Luke Christian Medical Mission. Dr. Wu in 1988 proposed to Dr. David Lee, a dentist who was in Fuller Theological Seminary, studying to be a full time missionary, to take up the challenge and establish a chapter of LCMM in the States, and to continue spreading the vision of medical mission in North America.
