Brian Teacher

Brian David Teacher (born December 23, 1954) is an American former professional tennis player. He reached career-high rankings of world No. 7 in singles, and world No. 5 in doubles, both in 1981. Teacher is best known for being a Grand Slam singles champion, triumphing in singles at the 1980 Australian Open, making him one of the few American men in the Open Era to capture a Grand Slam singles championship. Over the course of his professional career, Teacher won eight ATP singles titles and 16 doubles titles.

Prior to turning professional, Teacher played at the University of California, Los Angeles (UCLA). Playing for the UCLA Bruins from 1973 to 1976, he earned All-America honors in each of his four seasons and helped lead the team to multiple NCAA team championships.

Following his playing career, he became a touring coach on both the ATP Tour and the WTA Tour. He coached a number of singles players, most notably guiding British player Greg Rusedski from outside the top 80 into the world top ten and to the finals of the 1997 US Open in a little over a year. In addition, Teacher coached five players who reached the world No. 1 ranking in doubles: Jim Grabb, Richey Reneberg, Daniel Nestor, Max Mirnyi, and Mark Knowles. He has been inducted into several athletic halls of fame, including the Intercollegiate Tennis Association (ITA) Hall of Fame.

He currently runs the Brian Teacher Tennis Academy in South Pasadena, California.
