Molly R. Manley, Assistant Director


As OMI’s Assistant Director, Ms. Manley oversees the office’s day-to-day operations and programming. This includes implementation of the strategic plan, collaborating with campus and community partners, and general supervision of office staff. In addition, she is responsible for incorporating restorative practices within the office’s policies and procedures while also providing training, when necessary, in accordance with industry best practices.

A graduate of the University of Michigan-Dearborn, Ms. Manley completed a Bachelor of Arts in Political Science prior to graduating with a Master of Public Policy with a focus in Justice Reform in 2018. During her time as an undergraduate, Ms. Manley was recognized as a Campus Difference Maker. Prior to her role as Assistant Director, Ms. Manley worked as a Program Coordinator at OMI, having first joined the office in 2011 as a VISTA (Volunteer in Service to America), serving for two years in that role. As one of four authors that resulted in successfully earning the campus Carnegie Community Engagement Classification in 2015, she truly has helped develop OMI into what it is today.

Ms. Muzzin currently holds a Bachelor of Arts in Social Relations and Policy with a focus on Peace and Justice Studies.

Racial justice and dialogue are some of Ms. Muzzin’s biggest passions. University of Michigan’s Summer Youth Dialogues and the International Baccalaureate Dialogues on Diversity were particularly formative for her.

Ms. Muzzin was a student participant in the program herself in 2013 and is eager to help the program grow and evolve.

As a proud third-generation Detroiter, you’ll find Ms. Muzzin at Eastern Market or at the local Pure Barre studio on Griswold. When she is not at the office, Ms. Muzzin loves to cook, read, and care for her numerous plants at home. Ms. Muzzin is excited to incorporate her deep beliefs in grassroots, abundance, and strengths-based mindsets into the amazing work that OMI does.
