Career Grisham began karting at the age of six, competing until 2015. Racing mainly in her home state of California, Grisham became the second female winner of the IKF Lake Speed Achievement of Excellence in Karting award, as well as the IKF Expert designation after winning two national titles.

In 2016, Grisham made her car racing debut in the Spec Miata class of the NASA SoCal Division, in which she finished eighth overall with a best result of second at Buttonwillow. Continuing in the series for 2017, Grisham took four podiums to claim runner-up honors, as well as being the highest-placed Teen Mazda Challenge entrant. The following year, Grisham once again finished runner-up in the series, before being selected as one of four candidates for the Mazda Road to 24 Shootout.

Continuing in NASA SoCal for 2019, Grisham had a breakout year, taking six wins en route to her maiden title in car racing. Towards the end of the year, Grisham participated in the selection process for the 2020 W Series season at Almería, missing out on the grid, but later appeared as a guest driver in the series' eSports League.

Grisham then made a one-off appearance in the Mazda MX-5 Cup in 2021, before spending the rest of the year and 2022 competing in the World Racing League.

In late 2022, Grisham was one of two winners of the The Heart of Racing's female talent search and joined the team for the 2023 GT4 America Series. Sharing an Aston Martin Vantage AMR GT4 with Rianna O'Meara-Hunt, the other winner of the shootout, Grisham won both races at Indianapolis to end the year sixth in the Am class.
