What Fudoshin means

Meet the instructor
Matthew Lindahl
Owner / Instructor at Fudoshin Martial Arts.



Matthew Lindahl is the owner and instructor at Fudoshin Martial Arts in Plymouth. He began karate training in 1994 with his father under Master Kerry Kruckow. In 2002 he earned his first-degree black belt and began teaching part-time under Master David Younglove, Grand Master Gordon Franks, and Grand Master Pat Worley.
Matthew’s early black-belt teaching years were guided in part by Master David Younglove within the Twin Cities USA Karate tradition.
He promoted his first students to black belt in 2006, earned his fourth-degree black belt in 2011, and later served in the United States Army—including work as a certified Army Combatives instructor and a deployment to Afghanistan. After completing a bachelor’s degree in mathematics in 2018, he opened Fudoshin Martial Arts (KarateMN) in 2023.
Lineage
A Twin Cities teaching tradition.
Grand Masters Gordon Franks and Pat Worley—co-founders of USA Karate in Minnesota—are part of the instructional lineage that shaped Fudoshin’s black-belt teaching standards. Franks, a former PKA world champion in full-contact karate, and Worley, a nationally recognized competitor and instructor, guided Matthew’s advanced rank and early promotions of students to black belt.
“I’m so glad he is another trusted adult for my little guy who was struggling with focus and self control, and has improved immensely in these areas since starting karate.”
