Lyss Sterling

Lead Mediator


Lyss moved to Pittsburgh in July 2021 to pursue a Master’s degree in Social Work. As Lyss
began this journey, they realized that transformative and restorative justice work in the social
work sphere was severely lacking and underdeveloped. Lyss began their mediation journey as a
Community Mediator at Just Mediation Pittsburgh, hoping to hone skills that relied less on the
carceral judicial system and more on the power of community care and intervention. By
developing these mediation skills, she hoped to take this knowledge surrounding conflict and
community and further develop that in domestic violence advocacy.

Before working with the Just Mediation team, Lyss worked as a case manager and domestic
violence advocate for the Domestic Violence Center of Chester County. Domestic violence
advocacy has been a long, winding path for her that began back during her undergraduate years
in 2015 as a 24-hour hotline advocate at Centre Safe. Within these roles, Lyss’s responsibilities
included case management, weekly counseling, information and referral services, legal advocacy,
and emergency and transitional housing assistance.

Lyss’s major life goals are to continue expanding restorative justice practices, including
mediation, throughout their community and beyond. As Lead Mediator at JMP, Lyss hopes to
further develop programs that can meet members of communities where they are, especially as
these programs relate to intimate partner violence.

On her off time, Lyss enjoys film photography, reading, cooking, and watching their cats engage
in upmost shenanigans. Lyss has a Bachelor of Arts in Psychology and a minor in Spanish from
Penn State University.

Just Mediation Pittsburgh has over sixty-five community mediators trained to respond to the specific needs of landlords and tenants in housing disputes.
