Lilia Angel-Post

Assistant Director
Office: Faner 3239

Lilia Angel-Post joined the CESL team in Fall 2014. She has had the opportunity to help CESL students in many different capacities such as admissions officer, academic adviser, immigration specialist, substitute teacher, and, most recently, Assistant Director. She is a native of Colombia but has called the United States home since her undergraduate years. Lili’s first degree is in architecture but her time as a student worker at the Center for International Education instilled in her a love for the International Education field. Her passion for this field led her to eventually leave the architecture profession to pursue a Master’s in Teaching English as a Second Language. Since then, she has enjoyed teaching Spanish and English to speakers of other languages, coordinating migrant services, working as a medical interpreter, and helping CESL students reach their language and academic goals. Lili also helps with CESL recruiting trips, serves as the adviser for the Latin American Students Association, and participates in professional workshops offered by NAFSA, as a speaker or as a learner. In her free time, Lili loves to go for hikes in the Shawnee Forest with her husband and daughter. She also loves to spend time with friends while enjoying all the advantages of living in Carbondale, a small American town with a multicultural heart.
