Activstars Instructor

Sean (aka Colonel Flag) once taught a cheer routine using kata which is so cool like his favorite hero, Leonardo from the Teenage Mutant Ninja Turtles. He scared of spiders but loves the Beatles. A rare non-sugar cereal Chex eater, he dreams of taking a chill Alaskan Cruise.

Sensei Sean Milligan grew up in ACTIVSTARS starting classes under Hanshi Kraig Hollingworth at age 7.  He continued his training under Sensei Ron Kallam after Hanshi Hollingworth left to start an ACTIVSTARS branch in Kansas.  After earning his black belt, Sean went to college where he participated in Arizona State University’s Mixed Martial Arts Team.  After graduating, he became an instructor in 2009.

His current rank is second degree black belt in Toushi Kan, which is a mixed martial arts style consisting of Karate, Judo, Taekwando, Hapkido, and Kendo.  In addition, he is a certified American Black Ops Combat Arts Instructor.

Sensei Sean considers himself to be very lucky to have studied under accomplished martial arts instructors and very privileged to work with some of the world’s best instructors. He plans to mold many black belt students as well as coach students at high level competitions.
