HIS Foundation was first registered as a Christian non-profit organization in Hong Kong in 1992. Later, HIS (Holistic Integrated Services) Foundation was registered as a Christian 501 (c )(3) non-profit service organization in 1998 in the United States. It has a history of serving China for over 20 years. Its main work is to provide free, quality medical services for indigent patients in rural China. Every year many short-term medical mission teams formed by Christian medical professionals were sent to provide the much-needed out-patient and inpatient services. The main medical specialties include orthopaedic surgery, plastic surgery, internal medicine, rehabilitation, and ophthalmology. Most volunteers are self-funded and come from the United States, Hong Kong, and Australia. HIS Foundation also donates medical equipments and wheelchairs. Tens of thousands of wheelchairs were donated since 2006.
Another important work of HIS Foundation is education in rural China. Eleven elementary schools have been built. Hundreds of high school students have taken advantage of the scholarship program to complete their education. Every year special programs including English teacher training courses, a week-long youth camp, and a children summer program are offered and benefit many teachers and students.
