Andrew "The Dude" Dudderar

Professor Andrew Dudderar is a Brazilian Jiu Jitsu Black Belt under Amal Easton of Easton Brazilian Jiu-Jitsu. He is known for being impervious to chokes and for having a strong focus on the mental aspects of training. Despite his intimidating appearance, Andrew has a sincere and inspiring love for helping others achieve their goals in Jiu-Jitsu, and quickly became one of the most beloved teachers in the local community.

Andrew wrestled in high school before going on to play college football. He started training Brazilian Jiu-Jitsu in 1999 under the venerable Rafael Lovato Sr. He moved to Boulder in 2000, and began training with Amal Easton in 2001. After receiving his bachelors degree in Psychology from CU, Andrew moved to Rio De Janeiro, Brazil to live and train at the birthplace of the martial art for two years. Andrew then received his brown belt from the Gracie Barra patriarch, Carlos Gracie Jr. and his black belt from Amal Easton.

He’s been with us since September of 2019 and received his blue belt Winter of 2020, and purple belt in spring 2022. He’s always had a knack for teaching and showing new folks the ropes. We knew he’d be a great candidate to help us coach some orientation classes and cover class when necessary. His favorite submission is the Sliding Collar Choke and his favorite thing about Brazilian Jiu-Jitsu is learning self defense against bigger opponents and learning the resilience required to not give up in bad positions.

Off the mats he enjoys camping, playing music and going to concerts.
