    Lawrence "Shack" Shackelford

    Catalyst, Journalism, Introductory & Advanced Filmmaking Teacher​

    Though "Shack" hails from Virginia Beach, VA, he attempts to pass as Latino whenever possible (and he is not). He has, however, spent half of his life in South America and, when pressed, will convince you that Brazil is where his heart is and thus home. He holds degrees in Biology and Spanish Language from the University of Virginia and has earnestly surfed the curriculum throughout his 23 years in the classroom, teaching everything from foreign language and graphic design to Biology, Chemistry, and Physics. After living among (and producing a film on) the Xavante and Ashininka indigenous tribes of the Brazilian rain forest, his passion was discovered and his focus turned to developing courses that empower students to communicate with the infinite possibilities of filmmaking. Shack is an Apple Distinguished Educator, a Certified Pro Trainer in Final Cut Pro, a has-been (wannabe-rock-star), a foodie, and a lover of foreign languages, niche perfumery, and dark chocolate.

    Jay Londgren

    Catalyst Teacher

    Jay is originally from the great frozen state of Minnesota. A former farm kid turned city dweller, he now considers himself a TCA (third culture adult). Since leaving Minnesota, Jay has lived in Iowa, Singapore, Venezuela, South Korea and he's now back in Singapore all over again. Now in his 11th year teaching, Jay has taught music at all levels, from PreSchool Kinder-music to High School Wind Ensemble. He has degrees in Music, Education, Conducting, and, for some reason, English Composition. When not in rehearsals, grading recordings, reading AT assignments, or convincing Catalyst students to push themselves and their audience, he can be found running, cooking, traveling, taking photos or learning to fly a Cessna. Please note that if you ask him about his favourite podcasts make sure you have allocated plenty of time for the response.
