Sensei Simmons studied under Rod Kobayashi who himself studied directly under O-Sensei Morihei Ueshiba, the founder of Aikido. Robert then studied Taekwondo and Hapkido under Grandmaster D.K.Shin in San Francisco from 1991 to 1998 where he also taught at the dojang; he also studied Hapkido under his dear friend Max Yongwoo Lee who is the living incarnation of "indomitable spirit." After moving to Napa, he studied Taekwondo under Master Terry Brule from 2001 to 2005 where he was California state champion in his AAU division in both forms and sparring in 2002, 2003, and 2004. He formed the Napa School of Martial Arts in 2011 and the Sonoma School of Martial Arts in 2021. He continues his training in Taekwondo, Hapkido, and Kumdo under Grandmaster Shin at the head dojang in Belmont, where he achieved his 7th Dan and was awarded the ranking of Grandmaster in November of 2021. In addition to martial arts, he is a winemaker, consultant, author, art and antique collector, and is fluent in Portuguese, Spanish, English, and French.

Adam Traum’s teenage son, who is now a second-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 1st 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.
