She gained recognition for her series Velocity (1998), which featured her mother's paintings projected onto her body. Rossiter participated in the artist collective fierce pussy (1991), co-founded ART CLUB2000 (1992) in collaboration with Colin DeLand at American Fine Arts Co., and established Velocity Gallery (1997) in Brooklyn, where she exhibited emerging women artists.

A move to California in 2000 continued her photographic exploration of psychodramatic relationships and constructed reality with a deeper connection to nature. After witnessing the attacks in NY on September 11th, her work shifted as she began to negate the figure in her images, seeking instead to evoke an energy of time and place. In 2003, she made her last performative work in Amden, Switzerland, staging scenes of death and rebirth, moving from a perspective of resistance to a more expansive state of awareness.

In Los Angeles in 2006, she exhibited large-scale photographic and sculptural installations, creating immersive experiences where scenes of nature and architecture became portals. She photographed crystals, bodies of water, and flowering trees, interested in their abstract visual power and consciousness.

In 2010, Rossiter returned to painting, developing a process that disengaged the mind and allowed further experimentation with material and color. Since 2019, she has worked nomadically, creating series of abstract paintings in various locations including New York, Hawaii, Mexico and Paris.

Her current show at Febo & Dafne Gallery in Turin (March-April 2025)—her first exhibition of paintings—features works created by imprinting large paintings on paper onto linen canvases, leaving abstract and often layered mono-prints.

Rossiter has exhibited widely in Europe including Germany, Italy, Spain and Switzerland. Her work made with ART CLUB2000 from 1992-93 has been featured in retrospective exhibitions in Mexico at the Carrillo Gil Art Museum, in New York at the New Museum and ARTISTS SPACE, and in Switzerland at the Kunsthalle Zürich.
