The American began his career in the late 70’s before reaching the top of the American Road Racing  series in the early 80’s.  He decided to retire from the sport in the Summer of 1982 to concentrate on business commitments.

In 1986, he was talked into coming out of retirement and rode for Suzuki team in the GSXR National Cup series where by the end of the season he had racked-up 45 wins out of 51 races.  He joined the Kosar Racing Team for 1987 and competed in the AMA Superbike championship where he finished in fourth place overall, riding against the likes of Wayne Rainey and Kevin Schwantz.

The American got his big break in 1988 when he was signed by the team Yoshimura R&D of America, allowing him also to ride in it’s parent company Yoshimura of Japan in 1989, seeing him win both of the championships.

Doug then went onto the Ducati team, allowing him to race in not only the World Superbike Championship but also the AMA Championship.  He not only won the World Superbike Championship by 150 points but also made history by winning a record 17 victories during the season and claimed the title of AMA Pro Twins Championship.

Taking the crown for the second year running in the WSB Championship of 1992, he finished third in the AMA Superbike series.

In 1993, Doug rode exclusively for the Ducati Italy squad in the AMA Superbike series and claimed the title with two rounds still to run.

In 1994, Doug was given the chance to ride for the Honda Racing Corporation (HRC) on their new RC45 Superbike, finishing fourth in the championship. He only rode a handful of races for the team in the following year.

After leaving the Honda, Doug  joined the Suzuki Endurance Racing team riding a 750cc and also riding a 1100cc in the AMA Superteams series for Team Ebsco Suzuki.   He won the World Endurance Championship of 1997 alongside his team-mate Peter Goddard on the GSXR 750cc.  He won the World Endurance Championship again in 1998 but this time riding for the Honda Racing team on the RC45.

Doug, now 49,  has raced in various events throughout the years and is now offering his services to help others as an instructor at track days and day events in the United States.
