Meet Arianne

Arianne Slay is a lawyer, prosecutor, wife, mother, and longtime resident of our community, running to bring her experienced leadership to the Washtenaw County Prosecutor’s Office.

As a former Assistant County Prosecutor in charge of domestic violence cases, an educator of future lawyers and officers in the criminal justice system, and a respected city attorney, she values and works collaboratively with all parties in the criminal justice system – victims and defendants.

Raised in the Georgetown neighborhood on Ann Arbor’s South Side, Arianne is the proud daughter of two public servants – a county employee and a police officer. As a product of Ann Arbor’s public schools, attending Bryant, Pattengill, Tappan, and Pioneer, Arianne has spent her entire life getting to know, work with, and learn from members of our community.

After high school, she went on to receive a Bachelor of Arts and a Juris Doctorate from Michigan State University. She now lives in Ypsilanti Township with her husband Sean (a teacher) and their children.

Arianne chose to use her legal education to serve our community, as an intern in the Washtenaw County Public Defender’s Office, as a Program Coordinator at Community Corrections, for nine years as an Assistant Washtenaw County Prosecutor focused on prosecuting domestic violence, sexual assault, and other felony charges, and as Senior Assistant City Attorney for the City of Ann Arbor. As a prosecutor, she has appeared in the 22nd Circuit Court, all six Washtenaw County District Courts, and every treatment court in our community.

Arianne has built her career on working with victims, defendants, prosecutors, law enforcement, defense attorneys, judges, and non-profits to provide wraparound services for those individuals involved in criminal justice proceedings, and has always had a focus on reforming our systems to address the root causes of crime in order to protect her community.

In addition to her local service, Arianne has become one of the foremost experts in Michigan on domestic violence investigation and prosecution; she currently trains prosecutors and law enforcement officers across the state of Michigan on how to handle every aspect of these difficult and deeply personal cases.

Arianne values being an involved member of everything she does and is currently a member of the Washtenaw County Bar Association, Women Lawyers Association of Michigan, and the National Black Prosecutors Association, in addition to serving on numerous boards and task forces aimed at addressing disparities in the criminal justice system, and in our communities.

Arianne believes that the protection of the public means all people, no matter their race, ethnic background, immigration status, gender identity, sexual orientation, income level, or mental health status. If elected, Arianne would serve as Washtenaw County’s first female and first African-American County Prosecutor, a meaningful sign of the change that is occurring in our criminal justice system.

She recognizes that our county and our country still have a long road ahead to improve the justice system, but Arianne is committed to keeping our community safe while fairly leading the Washtenaw County Prosecutor’s Office and criminal justice system with experience-based reform.
