Erik was born to Jack and Diane Diffin in Mt Clemens, MI. Shortly after his birth, he and his family moved to Kernersville, NC, so his father could take a job with Purolator Facet, Inc. Erik grew up with two older sisters, Jessica and Kimberly.
He spent a large portion of his adolescence skateboarding. He helped to build an indoor skatepark/shop that eventually sponsored his skateboarding. He met a number of close friends through skating. They hung out, film and edited skate videos, took a road trip around the US in 30 days, and still remain friends to this day.
