In High School, his work was featured in the local newspaper, where he caught the eye of Disney and Hanna-Barbera animator Ruben Apodaca. Right out of High School he was offered a job at 2 major Animation Studios, Filmation and Hanna-Barbera.
It was off to Hollywood for Mac and Sib. They started their careers at Hanna-Barbera at the peak of Saturday Morning children’s broadcasting. From the Flintstones to Scooby-Doo, if you grew up in the ’80s and watched Saturday morning cartoons then you’ve certainly seen Mac and Sib’s work.
Over the next 20 years, Mac and Sib’s careers crisscrossed throughout various studios. Eventually, Filmation stole Mac’s talents from Hanna-Barbera. Mac worked on He-Man and the Masters of the Universe, Black Star and many other Saturday morning favorites.
