Maria Fassi tasted victory in the amateur ranks every year from 2015 to 2019, a run which included three Mexican Women’s Amateur crowns.
Fassi turned professional in May 2019, making her debut at the US Women's Open where she finished T12.
She picked up her first professional win in the 2020 NWA Classic, a Women's All Pro Tour event which took place while the LPGA Tour was on hold during the Covid-19 pandemic.
