Rosina D'Angelo: Program Manager, Costa Rica

Originally from Houston, TX, Rosina discovered a passion for international education as a teenager after spending a summer studying Spanish in Salamanca, Spain with ISA. Her love of language led her to pursue double majors in English and Hispanic Studies at the University of Richmond, where she had the opportunity to study abroad again in both Córdoba, Argentina and Alcalá de Henares, Spain. After graduation, she moved back to Spain and taught English for 3 years in the bustling city of Madrid and the beautiful island of Mallorca. Now that she’s back in Texas, she’s excited to advise ISA students preparing to set off on their own international adventures! In her free time, she loves cooking and baking, hiking, and exploring new cities.
