Born in Kroonstad, Orange Free State, South Africa, Allem was one of five children born to a wealthy family. He was introduced to golf by his father, when he was seven years old. Gary Player was a close friend of the family, and also encouraged the young Allem to play.
Allem opted to play golf professionally rather than attend college. During the early years of his career, he mostly stayed in South Africa to play. After finishing second in the NEC World Series of Golf, in 1987, Allem decided to play on the PGA Tour. His first PGA Tour win came at the Independent Insurance Open, in 1991. Two years later, Allem had a successful year on the Tour. He achieved victories at the Southwestern Bell Colonial and the NEC World Series of Golf, and ended the season in ninth place on the money list.
Ever since this year of success, Allem has been hampered by a series of medical problems. These issues have included a herniated disc, pericarditis, vertebrae problems and several heart attacks. As a result, Allem’s playing career has been limited, although he has played on the Champions Tour since 2007.
That same year, Allem was one of the three judges on the Golf Channel show, Fore Inventors Only.
Away from the golf course Allem is a family man, who lives in Florida. He is married to Jennifer, and the couple has four children.
As of the end of 2014, Allem had achieved three wins on the PGA Tour, amassing total prize money of $3,155,787.
