Collier also founded Citizens Advisers Inc., a mutual fund management company focused on socially responsible investing, before transitioning to large-scale art projects inspired by natural water surfaces.
[3][4] Written in 1976, and published in 1978, Collier produced a book about her teen-aged life entitled Soul Rush in which she recounts her spiritual development, experimentation with recreational drug use and Eastern mysticism as a teenager.

[10] After the sale, Collier established an investment office with Chula Reynolds[11] as well as an art studio in Sausalito, California using software and large scale machine tools [12] to making sculptural reliefs of water surfaces.
"[13] Collier drew a connection with her prior financial work stating that it allowed her " to know it was possible to develop software to model vast, turbulent, nonlinear data sets like money … and also, maybe, water in motion."
