Marchi was born in Knoxville, Tennessee, to Susan Kay Hester (née Taylor, born 1951).^[3] Her stepfather, Michael Hester (1957–2016), worked as a bio-medical engineer.^[3][4] She graduated from the University of Oklahoma with a bachelor's degree in theater,^[5][6] and started her professional acting career in 2000.^[7]

Marchi got her start in voice acting in Fruits Basket as Motoko Minagawa, and has worked on and voiced for a number of American adaptations of Japanese anime series, which include Black Cat as Rinslet Walker, Soul Eater as Elizabeth "Liz" Thompson, Sekirei as Uzume, Heaven's Lost Property as Mikako Satsukitane, Panty & Stocking with Garterbelt as Panty Anarchy, A Certain Scientific Railgun as Mitsuko Kongo, Rin: Daughters of Mnemosyne as Mimi, Strike Witches as Charlotte E. Yeager, Freezing as Rana Linchen, High School DxD as Rias Gremory, Witchblade as Masane Amaha and Death Parade as Chiyuki. She also writes the anime dub scripts and directs other Funimation actors.^[5]

In April 2013, Marchi joined The Funimation Show web series as a co-host.^[8]

On September 3, 2015, Marchi made her debut role for Sentai Filmworks as Neko Kuroha in Brynhildr in the Darkness.^[9]

On November 3, 2017, Marchi made her first non-anime role as Green Guts in Cartoon Network's OK K.O.! Let's Be Heroes.^[10][11]

On February 8, 2019, in response to the accusations of homophobia and inappropriate behavior being launched at voice actor Vic Mignogna, Marchi, along with voice actress Monica Rial, shared their own alleged experiences.^[12][13][14] Mignogna categorically denied these allegations, asserting that all interactions were consensual and lacked malicious intent.^[15] On April 19, 2019, Mignogna filed a lawsuit against Marchi, Rial, Ron Toye, and Funimation, claiming defamation and tortious interference. The lawsuit stemmed from public statements that Mignogna argued damaged his reputation.^[16] In his deposition, he described playfully touching Marchi’s hair as a compliment to her haircut, denying any sexual undertones and framing interactions as friendly. He provided a detailed account, admitting to a casual, playful action but denied any misconduct. He maintained that he had no intention of causing harm.^[15] On September 6, 2019, the civil case against Marchi was dismissed based on Mignogna’s status as a limited-purpose public figure, requiring a higher burden of proof for defamation.^[17] In February 2022, Marchi and Rial began a monthly podcast discussing their perspective on the defamation case.^[18]

Marchi's younger brother, Jean-Luc Hester, is also a voice actor.^[3][4][19]
