In Muong Sing, Dooley was the doctor and Rhine and Davis served as assistants. They had several local people who became students, and these students would administer the medicine as Dooley directed. This was important; it prepared Asisans to aid Asians not only then, but also in the future after Dooley was gone. Along with the students, Dooley had interpreters because they treated people who spoke many different languages and dialects that he, Rhine, and Davis did not speak. Dooley could speak French and Lao, and Rhine and Davis eventually learned to speak Lao. In order to communicate with the patients, Dooley, Rhine, and Davis often had to depend on one or more interpreters. The patient would tell an interpreter the problem, the interpreter would relay the message to another interpreter, and eventually the message would get to one of the three Americans, who would then tell the interpreter what to tell the patient. Sometimes this took quite some time, but eventually they were able to communicate and help the patient.

          Ngoan Van Hoang worked as the English-Laotian interpreter for Rhine and Davis. Originally from Vietnam, Hoang was a refugee in Laos. He had worked in a restaurant and took English classes. One of Dooley's friends knew that Hoang could speak English, so Dooley hired him to work at Muong Sing.

          The interpreters and students learned about America through their everyday routine: wake up, wash, eat breakfast, go to work, go home and eat lunch, go back to work, go home and eat supper, and then have discussions in the evenings on such topics as America, its people and its culture.

          Dooley, Rhine, Davis, the students, and the interpreters held "sick call" every morning. They treated the people of the village and those from surrounding areas who came to the hospital in Muong Sing. They treated many different ailments, including tuberculosis, pneumonia, malaria, small pox, whooping cough, leprosy, beri-beri, respiratory infections, vitamin deficiencies, malnutrition, and much more. They usually performed surgeries in the afternoon.

          They also delivered babies, rotating who did the deliveries. Unbelievably, all the babies Davis delivered were boys, and all the babies Rhine delivered were girls, except one boy who was actually Davis' patient. Eventually the people would only see Davis if they wanted to have a boy and Rhine if they wanted to have a girl. They would avoid the other man, believing he had something to do with determining the sex of the child.

          In addition, they held classes to teach the people basic hygiene, which would help prevent some of the illnesses. They also held language classes to teach the medical staff, local officials, and military men not only how to speak English, but also about freedom and citizenship in America.

          When a chief from a different village visited Dooley in Muong Sing, Dooley gave the chief a first-aid box and trained him how to use the items such as iodine, bandaids, antimalarials, and antibiotic ointment for wounds. Dooley had given dozens of these first-aid boxes to chiefs, but he did not know if they were being used. One day, several men brought in a man who had been mauled by a tiger. When Dooley went to look at the wounds, he found compresses of the antibiotic ointment on the wounds instead of the usual witch doctor treatment of bettlenut, tobacco, cow dung, and monkey fur. This reassured Dooley that at least some of the chiefs were using the first-aid boxes.

          Dooley helped establish substations of the Muong Sing hospital in surrounding villages. Lao military students who had graduated from Dooley's training ran these substations, and they helped the villagers become healthier with their new knowledge.

          Dooley had built and worked at a hospital in Nam Tha, Laos, in 1957. After Dooley went to Muong Sing and trained some students, he sent one of them to run the hospital in Nam Tha. Dooley, Rhine, and Davis took turns monitoring Nam Tha and delivering medication.

          At first, many of the Laotians were skeptical of the three Americans and their medical treatment. However, when people came to "sick call" and got better, people quickly overcame their fear of Americans and their medical treatment. Eventually, most of the people accepted Dooley, Rhine, and Davis as part of their community because of the medical care, the classes they provided, and their ability to speak Lao. People at the clinic revered the Americans because of their compassion and their medical skills. The Americans did observe some cultural practices. Dooley allowed the patients' family members to stay at the hospital even though in America this would not typically be allowed.

          Dooley, Rhine, and Davis also treated the people with no discrimination, which was unusual in Southeast Asia. The people discriminated against each other because each tribe thought it was better than the others. However, after seeing the Americans and the local students treating everyone the same at the hospital, the people began to treat each other more equally.
