After immigrating to the United States in 1976, he received his MBA and taught graduate students. He had a successful career of over forty years in the computer networking industry. Siyoung was an avid lifelong learner, studying online theology at Yale Divinity School, Princeton Theological Seminary, and Union Theological Seminary.
