Dr. Wilberg was born on February 20, 1955, in Orangeville, Utah, and raised in Castle Dale, Utah.
- As a boy living in the small mining community of Castle Dale in central-eastern Utah, 4-year-old Mack Wilberg learned to play the piano by ear. His fascination with the instrument grew until it bordered on obsessive. Mack’s mother, concerned about balance in her son’s life, sometimes had to force him to break from the piano and go outside and play. He would go outside to appease her, but then he would go to his neighbors’ home, where he would ask to play their piano. Music was more than just diversionary for him; it was his life.
- His family was supportive of his fervor. Every week, his mother would drive him 40 miles outside of town to where he could receive quality instruction from a gifted piano instructor. When he was 10 years old, his grandmother took him to see the Mormon Tabernacle Choir perform. He says that as he entered the threshold of the Tabernacle, the effect on him was tangible. “It felt like I had walked into a wall of glorious sound,” Mack says. Little did he know that eventually that same choir would perform his own musical creations as he stood at their fore with a conductor’s baton.
He and his wife, Rebecca, are parents of four children.
