She volunteered to host a Russian student and participated in the reciprocal exchange to Kaliningrad, Russia, knowing none of the language and little of the culture. It opened her mind to different world views and gave her a whole new appreciation of what hospitality and sacrifice meant. She was always a curious, passionate learner and became a curious, passionate educator, eventually transitioning to a career in instructional design. 

Catesby majored in Russian at Georgetown University and lived abroad for several years.
