From early on, Donald was into anything with an engine. From racing motocross, to asphalt oval track, and heavily modifying his four wheel drives. In 2009, he wanted to go bigger than ever and bought his first tube chassis monster truck- creating Titan and taking his adventures nationwide. Starting off at local shows, he was soon recognized by Monster Jam and started competing in their events.

In 2012 he was invited to the Monster Jam World Finals in Las Vegas to compete in the first ever Young Guns Shootout. Since then, he has competed in Monster Jam's World Finals 4 times.

Epidendio and Titan continue to rise and be competitive with the best in the world, performing in front of half a million screaming fans a year. He also greets fans with public appearances and one-on-one autograph sessions which include Pit Parties prior shows, post-show autographs, displays with Titan, charity events and extensive national media.
