David Witt (born June 2, 1973) is an American former professional tennis player best known as the former long-time coach of Venus Williams. He is currently coaching Jessica Pegula. He enjoyed a successful junior career, during which time he won the USTA Boys' 16s Clay, Hard and National Championships and was the top-ranked under-16 in the USTA in 1989.[1] He was also a semi-finalist at the US Open Junior Boys Singles event in 1991.[2]
In 2002, while working as the resident pro at the Deerwood Country Club in Jacksonville, Florida, Witt was approached by the Williams sisters to act as a hitting partner during their participation at the Bausch & Lomb Championships at nearby Amelia Island. In 2007, they asked him to accompany them to Charleston, South Carolina for the Family Circle Cup.[3] Since then he has acted as a travelling hitting partner for both women,[4] most notably for elder sister Venus.[5][6] In December 2018, Venus ended the 11-year partnership.[7] Since July 2019, David Witt is coaching Jessica Pegula.[8]
