Our Story
In 1977, David and Diana Sun immigrated from Taiwan to America as a young married couple in pursuit of a new life with greater opportunity. Shortly thereafter, they settled in Orange County where they put down roots and raised their two children. For the past 40 years, they have proudly called Orange County their home.
In 1987, David co-founded Kingston Technology, which became the world’s largest independent manufacturer of computer memory products. Kingston still operates today with its corporate headquarters in Fountain Valley, California and manufacturing facilities and offices across the globe.
In 1999, David and Diana founded the Sun Family Foundation (the “Foundation”) with the vision of sharing their good fortune with the local communities that have supported their family and business ventures.
Since the Foundation’s inception, it has primarily focused on providing educational opportunities for underserved youth. The focus on education was inspired by David’s late mother, 戴廣源 (“Guang Yuan”), who was a beloved and popular high school biology teacher in Taichung, Taiwan. Guang Yuan served as a confidant and trusted advisor to thousands of students throughout her 30 year teaching career, while also raising three children as a single mother. In 2011, in his mother’s memory, David and Diana formed the Guang Yuan Charitable Foundation in Taiwan, which has provided over 7,000 scholarships to underprivileged elementary, junior high school, senior high school, college and vocational students across the country of Taiwan.
The Foundation is now run by two generations of family members, with its next generation now holding leadership positions and helping to shape the Foundation’s future strategy towards philanthropy and grantmaking. In recent years, the Foundation has expanded its grantmaking to support not only education, but also organizations that provide services to underserved individuals and communities. The Suns envision using the Foundation to bring the family closer together across generations and to pass on David and Diana’s legacy of philanthropy.
