Harry grew up in Alamo Heights, Texas where he started racing karts at 13 years old. Racing is in the Gottsacker blood, as his grandfather and his father were involved in IndyCar and NHRA teams as he was growing up. His abundant talent was immediately evident as he won a World Championship race at Daytona International Speedway – in his first season of racing. His second season he returned to Daytona to defend his title, winning the World Championship race a second time and this time racing in an additional class, where he finished on the podium in 3rd. By the time he was 14, he was a regular winner in multiple classes and became a factory driver for the Intrepid Driver Program. This afforded him a trip to Italy, representing the USA in the KZ2 World Championship, and a factory ride again for the next season.
At age 16, Harry moved to car racing in both the Red Bull Global Rallycross and the Pirelli World Challenge. Running only partial seasons in both series, he was able to finish on the Podium at Utah Motorsports Campus and 5th at Laguna Seca in his Ginetta G55 GT4. He was also able to take Top 5 finishes at the Red Bull GRC events at Dallas and North Carolina in his Olsbergs MSE Rallycross Lites car.
For 2017, Harry raced several races in British GT for Century Motorsport in a Ginetta G55 GT3 with a Silver Class win at Oulton Park. Additionally, he debuted on American soil in GT3 machinery for The Racers Group in a Porsche 991 GT3R at Circuit of the Americas in the IMSA WeatherTech Series. Harry also ran several races in Pirelli World Challenge GTS in his familiar Ginetta G55 GT4 and earned dual podium finishes at the Mid Ohio Sports Car Course.
Posting strong finishes in GTS is where he caught the eye of Racers Edge Motorsports Team Owner Jon Mirachi, who was impressed by his speed and maturity on the track. Harry piloted the SIN R1 GT4 in the Pirelli World Challenge GTS Sprint and GTS SprintX championships during the 2018 Season. Harry was able to win at both Portland and Utah and finish on the podium at COTA, Long Beach, Lime Rock, and Road America. These strong results led to a 2nd place finish in the GTS Overall Championship and the GTS SprintX Championship.
