The Office of Multicultural Affairs (OMA) promotes Lehigh's commitment to diversity and inclusion through resources and advocacy for students from historically marginalized populations. Founded in 1992, the OMA’s goal is to help retain and recruit these students while enhancing their experiences through cultural programming, workshops, support groups and education.

OMA programming promotes the intellectual stimulation, self-exploration, and personal growth of students as they engage with multiculturalism within and outside the Lehigh community. There are experiential learning trips and opportunities for identity exploration; leadership development workshops; academic success seminars; mentoring programs; and collaboration with faculty, staff, and alumni to enhance multicultural competency.

OMA director Tyrone J.A. Russell, a former residence life coordinator, launched the underrepresented men's empowerment organization known as MOCA and introduced a number of culturally diverse events to campus. He also co-chairs the university’s MLK Committee, which coordinates a yearlong series of events dedicated to social justice issues.
