Catesby Porfirenko Our Team

Instructional Designer 

A monumental turning point in Catesby’s life happened at age 16. “The Russians were coming” to Fredericksburg, VA, the small town where she and her family lived. 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. She got her M.Ed. in TESOL and taught English as a Second Language (ESL) in San Diego, CA, and Northern Virginia. She received a Graduate Certificate in e-Learning from George Mason University in 2019 and appreciates the challenges and rewards of education utilizing multiple platforms. She draws from her experience as student, teacher, trainer, and instructional designer and focuses on student-centered learning in whatever she creates, always aware of ever-changing technology and her responsibility to meet the needs of the target audience. 

Catesby is humbled and excited to be a part of the Stearns Center staff and Mason community. In her free time, she watches Russian movies, listens to country music, exercises in nature, does Pilates, and travels. Learning to play the ukulele is her next endeavor.
