Peter has been working to promote men’s accountability and end commercial sexual exploitation and other forms of gender-based violence for over thirty years. In the early 1990s, he co-founded the Sexual Exploitation Education Project in Portland, Oregon, where he created one of the first sex buyer intervention programs in the country. During that time, he also worked with the Portland Women's Crisis Line to integrate the issue of commercial sexual exploitation into a comprehensive middle and high school program to prevent gender-based violence. 

In 2012, he co-founded the Organization for Prostitution Survivors (OPS) with survivor leader Noel Gomez in Seattle. As OPS’ Director of Men’s Accountability, he launched the 10-week sex buyers intervention program Stopping Sexual Exploitation and co-coordinated the King County Ending Exploitation Collaborative. Presently, Peter lives in Western Massachusetts and directs Modeling Equality, a project of OPS to catalyze the creation and implementation of policies and practices across multiple sectors that address commercial sexual exploitation through an Equality Model framework. 

The Organization for Prostitution Survivor’s mission is to accompany survivors of prostitution in creating and sustaining efforts to heal from, and end, this practice of gender-based violence. 

OPS is survivor-founded, survivor-led, staffed predominately by survivors, and we elevate survivors in all we do.

OPS was founded in 2012 with the specific mission to provide Commercial Sexual Exploitation (CSE) victim services, focusing in 3 areas: 

1) Creating a supportive and restorative community for survivors to exit from prostitution and build new lives; 

2) changing cultural norms of gender-based violence through men’s accountability programming; and 

3) providing community training and education on CSE.

Incorporated in 2013 by Noel Gomez and Peter Qualliotine, OPS became a social service agency and agent of social change charged with the task of carving out a safe space for survivors of prostitution and trafficking to heal from these systems of gender-based violence and lead the movement towards greater equity and justice.
