[2] After being denied from Derner the first time she applied, Greene attended the doctoral program in educational psychology at Marquette University before she was diagnosed with a benign brain tumor.
[2] During her doctorate, Greene worked at Kings County Municipal Hospital Inpatient Child Psychiatry Division in Brooklyn.
[2] Later, in 1982, Greene started working at the Inpatient Child Psychiatry Division at Kings County Municipal Hospital in Brooklyn, New York where much of the staff was predominantly white.
[2] When working in the Inpatient Child Psychiatry Division at Kings County in 1991, Greene was mentored by Chief Psychologist Dorothy Gartner.
Greene attributes her success in this position to the encouragement she received from department chair Jeffery Fagen and Dean David O'Connell.
Greene credits her superior and other colleagues on their encouragement for her to write on the topic of psychotherapy in marginalized African American, LGBTQIA+ communities and develop inclusive public health frameworks in feminist psychology.
[2] Additionally, Greene was recently named as a founding co-editor for the St John’s Institute for Critical Race and Ethnic Studies journal.
Her main focus has been on the complexities of the human identity, believing that the framework of a person should not be limited to a strict gender.
Greene's advancement in psychology has shown people should not be marginalized based on race, gender, or sexual orientation.
She argues that the convergence of gender, race, and sexual orientation shapes the social inequality women of color endure day-to-day.
[6] Greene suggests clinicians working with people of color, specifically African-American women, should take precautions to not prematurely dismiss complaints about racist and sexist discrimination.
Greene often cites the importance of training therapists to be culturally-aware and capable of embracing their own ignorance and gaps in knowledge.
[7] Greene's work focuses mainly on the therapeutic assessment period during which the therapist begins to understand the individual's experience with racism and relationship to their own race.
Similar to Greene's other work, the book attempts to construct models for better understanding the individual, rather than the collective group.
