While working on his Ph.D., Professor Guerrero worked at Dartmouth College as an Assistant Professor of Operations Manager in the Amos Tuck School of Business Administration. In 1986 he joined the University of Notre Dame College of Business Administration as an Assistant Professor of Operations Management and Information Systems.

Above all, his heart brimmed with a calming joy, which he effortlessly shared with all, including his loved ones and the countless students and colleagues whose lives he touched. Hector possessed a profound and inviting presence that left an indelible mark on all those fortunate enough to cross his path. Whether it was during his travels to his cherished paradise, Isla Mujeres, Mexico, with family in Texas, at home in Williamsburg, or his recent years spent in Maryland, Hector built meaningful connections and showed care and generosity to everyone he encountered. Kind, intelligent, and possessing a unique ability to brighten the spirits of others, Hector Guerrero was a beacon of light, with a life fully lived. He will be deeply missed.
