Early Life
Born on December 22, 1970, in Taipei, Taiwan, Elder Wu moved with his family to Santa Cruz, Bolivia, when he was just 10 years old. This move proved to be a pivotal spiritual turning point.1
Shortly after arriving in Bolivia, his sisters met the missionaries through friends. Elder Wu began meeting with them as well and was baptized at age 11. At age 14, his family moved again, this time to Buenos Aires, Argentina. Adjusting to new languages and cultures twice in one decade was challenging, but Elder Wu noted to Church News, "I lost something to have better things in a better way of the Lord."2
Education and Marriage
He returned to his roots for his mission, serving in the China Hong Kong Mission. Afterward, he attended Brigham Young University–Hawaii, where he earned a degree in business management.3
In 1995, he returned to South America to marry Marcela Beatriz Castellani in the Buenos Aires Argentina Temple. Sister Wu is a native of Argentina, and together they have raised three children.4
Professional Career
Before his full-time Church service, Elder Wu worked in the international business and technology sectors. His ability to speak Mandarin, Spanish, and English fluently allowed him to serve as a bridge between different global markets, a skill that has translated directly into his ministry for a global Church.
Teachings
In a September 24, 2025 devotional at BYU-Hawaii, Elder Wu talked about becoming a lifelong disciple of Christ. He told students how to become disciples: "by intentionally choosing to live His doctrine each day. It is a continuous process, not merely a series of isolated occasions."5
He concluded that devotional with a simple invitation and promise:
"I thank the Lord for allowing me to be here with all of you. You are precious sons and daughters of God. Heavenly Father loves each one of you. He earnestly desires to bless you. I invite you to pray daily, to have personal interviews with Him. Express your challenges to Him and ask for His help. He will listen, and He will answer."
