Head Instructors

Troy Gerkey is co-owner and one of the head instructors at Infinity Martial Arts – Sun Prairie. He is a 1st degree black belt and started martial arts in 2011.

As a kid, Mr. Troy, always wanted to try martial arts, but was intimidated by pushups. Inspired by his son, Emmett, earning an Infinity black belt, he began taking classes as an adult.

Mr. Troy’s favorite part of martial arts is sparring and the sense of community gained from training with fellow students. His goal is to teach martial arts in a way that develops focus, respect, and leadership among other positive traits.

You’ll hear Mr. Troy often say, “Don’t let one bad day keep you from reaching your goal.”

Jeff Spridco is also a co-owner and one of the head instructors. He is a 5th degree black belt and started martial arts in 1989.

After watching The Karate Kid for the first time, 5-year-old Mr. Spridco knew he wanted to take karate. Now, Mr. Spridco is a 5th degree black belt and an instructor for the past 15 years. As a teacher, Mr. Spridco enjoys passing on the knowledge he’s gained in his many years of martial arts training.

Mr. Spridco’s favorite thing about martial arts is executing all of the different styles meshed together for the school’s curriculum. In traveling across the country, Mr. Spridco has been able to train, teach and compete with world-renowned martial artists.

Mr. Spridco will tell you that “Practicing outside of school for 10, 15 minutes a day makes a huge difference.”
