Born in Narrabri, New South Wales, in 1970, Stoltenberg held an Australian Institute of Sport scholarship and in 1987 won the boys' singles at the Australian Open, finishing the year as the world's No. 1 junior. He turned professional the same year. He won four tour singles titles between 1993 and 1997 (Manchester, Birmingham and Coral Springs twice) and five in doubles, and reached No. 19 in singles in October 1994 and No. 23 in doubles. He played in the Australian team that lost the 1993 Davis Cup final to Germany, finished with a 9-5 Davis Cup record and played the 1996 Olympics in Atlanta. He retired in 2001, coached Lleyton Hewitt from December 2001 to June 2003 and has worked as a Tennis Australia coaching consultant since 2010.

Anecdotes
The person behind the player.
Narrabri, New South Wales
An antbed court on the farm
He started playing at the age of ten on an antbed court, made from crushed termite mound, on his father's cotton farm in the far west of New South Wales. From there he went to the Australian Institute of Sport, and in 1987 he finished as the world's No. 1 junior.
In the boys' final of the last Australian Open on grass he beat Todd Woodbridge 6-2, 7-6. The two then won the doubles together, and the partnership went on to take five junior major doubles titles: the Australian Open and Wimbledon in both 1987 and 1988, and the French Open in 1988.
Darkness stopped his quarter-final against Goran Ivanišević with Stoltenberg two sets to one up. On the resumption Ivanišević had three break points in the second game of the fourth set but could not take one, and Stoltenberg won the tiebreak 7-3 to reach his first major semi-final.
Seeds fell so fast that year that Todd Martin, at 13, was the only seed left among the last four. Stoltenberg met Richard Krajicek, who had beaten him in the first round of the Australian Open that January. Krajicek won again, 7-5, 6-2, 6-1, and went on to take the title.
When Lleyton Hewitt beat David Nalbandian in the final, he climbed through the stands to the guest box, as Pat Cash had done in 1987, and embraced his coach, Jason Stoltenberg, before going back down to collect the trophy. Hewitt said afterwards that he kept looking at the scoreboard to see if it was real.
His time with Hewitt lasted about 18 months, from late 2001, and took in the 2002 Wimbledon title. He later returned to coaching through the national federation: from 2010 he worked as a Tennis Australia consultant with several Australian players, Ash Barty among them.
