Yuèshān-guan [ 月山館; Moon Mountain Hall ] is a private training activity near Seattle that is centered around the cultivation of skill at traditional approaches to internal martial arts.

I maintain a formal practice of traditional Wu (吳) Taijiquan, Yin Baguazhang and Hebei Xingyiquan. This includes foundational exercises, posture training, solo form practice, partner exercises and applications. I place a strong emphasis on traditional methods of sword, saber and spear associated to these arts in my training. I practice as part of formal lineages of these arts preserved in Yin Cheng Gong Fa [ 印誠功法 ] North America.

I also have trained in traditional sword methods from Japan, including surviving lines of Shinkage-ryū such as Jiki Shinkage-ryū — that art in particular was influenced by Ming dynasty Chinese sword practices and I attempt to practice it in a manner that is consistent with my knowledge of internal martial arts principles. Yuèshān-guan is read as Gassankan in Japanese. I practice kenjutsu independently and mentor a small group in Seattle.
