Early Life and Background
Isaac Kitzmiller was born on February 26, 2009, in Maysville, West Virginia. Growing up in a region with a deep appreciation for short-track racing, he was introduced to motorsports at an early age through his family. His father, Jason Kitzmiller, is a fellow racing driver who currently competes full-time in the ARCA Menards Series for CR7 Motorsports, giving Isaac a direct connection to the sport from childhood.
Raised around race shops and short tracks, Kitzmiller developed an early passion for stock car competition. The influence of his father’s career helped shape his understanding of race craft, car preparation, and the discipline required to compete at higher levels. This foundation allowed him to progress quickly through junior racing ranks and gain recognition as a promising young talent.
Path to NASCAR
Before reaching the ARCA national level, Kitzmiller built his resume in several developmental stock car series. He competed in the CARS Pro Late Model Tour, the Grand National Super Series, the INEX Nashville Spring Series, the INEX Summer Shootout, and the World Series of Asphalt Stock Car Racing. These series are widely regarded as proving grounds for young drivers aiming to climb the NASCAR ladder.
Since 2023, Kitzmiller has been a driver in the Team Hornaday Development program, which was founded in 2022 by Candice Hornaday, daughter of NASCAR Hall of Famer Ron Hornaday Jr. The program is designed to mentor emerging short-track talent and provide guidance on and off the track. Participation in this program gave Kitzmiller access to coaching, exposure, and structured competition that helped prepare him for national ARCA competition.
Isaac Kitzmiller Career
Early Career
Kitzmiller’s earliest documented national-level step came in 2025, when it was announced he would participate in the pre-season test for the ARCA Menards Series at Daytona International Speedway. He drove the No. 97 Chevrolet for CR7 Motorsports during the test, gaining valuable superspeedway experience. The test served as a formal introduction to the ARCA Menards Series environment and signaled his transition from regional and developmental racing to a national platform.
That same year, Kitzmiller made his ARCA Menards Series East debut at Five Flags Speedway, driving the No. 79 for CR7 Motorsports with ACR Motorsports.

At sixteen years old, Kitzmiller became one of the youngest drivers to capture the East Series crown. The championship validated his development path and positioned him as a rising prospect in American stock car racing.
