Our History
MSI Professional Services International is a Christian non-profit charitable organization founded in 1994 to provide development assistance to China. The change of name in 2001 reflected our increasing scope of work from medical services to include community development, English education, business administration and management training, youth work, and livestock projects. In 2017, MSI successfully re-registered our Sichuan and Yunnan representative offices and continued our work in both provinces.
In this new decade, our long-term workers serving in China have been presented with opportunities, together with local volunteers, to serve the marginalized: those with special needs, disabled, mentally challenged, elderly etc. From sending only short-term teams in our early years, we now have long-term workers and their families stationed in Inland China, either in front-line service or in pre-service language studies.
With God’s help, MSI continues to seek to share the love of Christ through the witness of our lives as Christian professionals.
Our Founders

His 10 years of service as founding president of MSI gave him many opportunities to work with officials from the central government as well as with provincial and grassroots leaders. The depth of their acceptance of and respect for him was reflected in the nickname they had given him (‘Overseas Chinese’) and in conferring to him an honorary citizenship.
