John was born and raised in Encino, California. As an aspiring jazz bass player, he attended the Musicians Institute in Hollywood. After graduating, he worked for a drywall contractor, where he learned the trade. Applying the knowledge he gained has become useful in his career as a public adjuster.

Determined to switch into a position that would allow him to help our clients more directly, he worked as an inventory specialist for a short time before becoming a licensed public adjuster.
