Dr. Marcy Leroy Ditmanson, the son of American missionaries Fred and Emma Ditmanson, grew up in China, and was imbued with a deep love of China and its people.

After completing his medical degree in the USA in 1957, Dr. Ditmanson came to Formosa, where his new wife also played a vital supporting role in his subsequent achievements – he first established a clinic in Chiayi in 1958 to bring mercy and hope to his many patients, and subsequently opened the thirty-bed Chiayi Christian Hospital (CYCH) in April 29, 1962.

With God's grace and many people hard work, Chiayi Christian Hospital (CYCH) has expanded to one thousand bed fifty years later.
