During his career as a player, Gullikson won 16 top-level doubles titles, ten of them partnering with his identical twin brother, Tim Gullikson, who was also a noted coach. Tim coached the then number one player in the world Pete Sampras before Tim was diagnosed with brain cancer in 1995, and died in 1996. The brothers were runners-up in the men's doubles competition at Wimbledon in 1983. Gullikson also won the mixed doubles title at the US Open in 1984, with Manuela Maleeva.
His best performance at a Grand Slam came when he got to the quarter finals of the 1982 US Open, defeating John Alexander, Jérôme Potier, Chip Hooper and Jaime Fillol before losing to Guillermo Vilas.
Gullikson won one top-level singles title (at Newport in 1985). His career-high rankings were World No. 34 in singles and World No. 4 in doubles (in 1984 and 1983 respectively). He retired from the professional tour in 1987.
After retiring as a player, he became one of the original members of the United States Tennis Association Player Development Program, coaching players such as Todd Martin, Jennifer Capriati and Andy Roddick. He served as Director of Coaching for the program from 1997 to 2001.
Gullikson was the United States Davis Cup Captain from 1994 to 1999. He captained the teams that won the Davis Cup in 1995 and were runners-up in 1997. In 1996, Gullikson was coach of the US men's Olympic tennis team, and guided Andre Agassi to winning the Olympic Gold Medal in Atlanta.
From December 2001 to February 2002, Gullikson briefly coached Pete Sampras.
