Adam Traum’s teenage son, who is now a third-degree black belt inspired him to take up taekwondo. Watching classes from the sidelines for years gave him a head start when he began taking lessons via Zoom during the COVID-19 pandemic. With the excellent instruction of Grandmaster Morey, Mr. Adam learned the fundamentals of taekwondo and constantly aspires to a higher level.

Although he is relatively new to the sport, the osmosis of watching his son, plus his childhood experience with judo, has allowed Mr. Adam to reach his advanced belts in a relatively short time.

Following the practices of Grandmaster Morey, Mr. Adam focuses on core fundamentals that are the cornerstone of taekwondo. He takes his role as an instructor seriously, preparing his students not only for their upper belts but to also hold the values of taekwondo as they go through life.

Mr. Adam is a 2nd Dan black belt and has worked diligently to improve as a martial artist, and is proud to represent Hwa Rang Kwan and the Sonoma School of Martial Arts.

Mr. Adam makes his living as a musician working as an instructor, clinician, performer, songwriter and music producer. His passion for excellence in music dovetails to the standards and fundamentals of taekwondo.
