About Us

Ginny McCarthy


Ginny is originally from St. Louis, Missouri. After earning her BA in Spanish and Theological Studies from Saint Louis University, she lived in Mexico, completed her Master of Divinity degree from Weston Jesuit School of Theology (now Boston College School of Theology and Ministry), lived and worked in Spain, and then returned to Chicago, which she now calls home. Upon arrival at Loyola in 2008, Ginny began her time in University Ministry but also held a charge to begin the Center for Community and Global Health (CCGH) with colleague Dr. Amy Blair. After several years full-time in CCGH, Ginny felt drawn to return to University Ministry to serve the students, staff, and faculty of the Health Sciences Division. Her areas of interest include reflection, global health, social justice, service immersion, community engagement, and Ignatian Spirituality.
