After repeated encouragement from her friends, Lillian Dickson established the non-profit Mustard Seed, Inc. organization in order for her donors to apply for tax deductions  in 1954 and founded The Mustard Seed Mission to continue her work in Taiwan in 1962. Medical missionary work 
Upon Dickson's return to Taiwan, her intent was to evangelize the Taiwanese children. However, it was her medical missions that attracted her American donors. While she was not herself a licensed medical professional, Dickson's organization provided medical care and promoted hygiene through several missions executed over her lifetime. Some examples of missions included: developing mountain clinics, building a church in a leper colony, and establishing a  clinic. Lillian Dickson's medical missionary work started with her focus on the leper patients and their children in the leper hospitals. When the children remained with their parents who were affected by leprosy, it was evident the children were at high risk of contracting the disease. Dickson found that when the children were separated at birth from their parents and were permitted to grow healthy. Hence, Dickson established a An-Lok Babies' Home to house the newborn babies with parents who had leprosy. From then on, Lillian Dickson went to create expansive leper colonies, and other clinics that focused on other diseases affected by the aboriginal people of Formosa.
