Mandi's professional background is in production management and line producing for independent film and TV. She joined the Director's Guild of America in 2016 as a UPM. Shifting her focus to creative endeavors, Mandi wrote and directed her first short film called OLD FASHIONED, which premiered at the 2017 Alameda International Film Festival and screened at Hollyshorts Monthly Screening Series in early 2018. Around that time, Mandi was writing a narrative feature script based on her childhood competing in pageants, when controversy struck the Miss America Organization. Seeing a community she cared about affected, Mandi put the narrative project on hold to investigate the changing times of Miss America culture. Mandi would later receive the Emerging Artist Award for SAVING MISS AMERICA at the 2018 Alameda International Film Festival and continues to develop the project full time.
Mandi is from Los Angeles originally and now resides in Oakland with her husband and producing partner, Joe Matarrese.
