About
JSK TaeKwonDo offers TaeKwonDo and other martial arts training that includes self defense skills and a focus on child development. Classes follow a structured curriculum and are described as disciplined, dynamic, demanding, and fun, with an emphasis on the idea that everyone can be great when they put their heart, mind, and body into it. The program teaches the original traditional ITF TaekwonDo developed and taught throughout the world by the late General Choi Hong Hi, Grandmaster and founding father of TaekwonDo.
• Ages: 5–18 years old
• Schedule: Class options Monday–Thursday afternoons and evenings, and Saturday mornings
JSK TaeKwonDo is open Monday through Thursday from 3:00 pm to 8:00 pm and on Saturday from 10:00 am to 1:00 pm, and is closed on Sunday. Families can book a free trial class.
The leadership team includes Mr. Joe Karstadt (Owner, Founder, Head Instructor), Mr. Josh Karstadt (Head Instructor), and Mrs. Kate Karstadt (Owner, Director). Mr. Joe Karstadt is a 6th Degree Black Belt who has been training in TaeKwonDo for over 35 years, is a member of the U.S. TaeKwonDo Team, has competed successfully in 10 international competitions, holds more than 25 national championship titles, was a member of the U.S. Men's TaeKwonDo Team that won 2 gold medals at the 2004 ITF World Championships in South Korea, and is a member of the Official TaeKwonDo Hall of Fame. Mr. Josh Karstadt is a 4th Degree Black Belt who has been exposed to martial arts for over 17 years, is a member of the U.S. TaeKwonDo Team, has competed in 11 international tournaments, holds 14 U.S. national titles, and is a World Cup medalist.
JSK TaeKwonDo states that it is dedicated to teaching the highest quality of martial arts available in its areas to students of all ages and abilities, with classes that are disciplined, structured, and dynamic. The structured curriculum is described as helping students set goals and experience the satisfaction of reaching them.
One parent, Scott M., shared that his son started taking TaeKwonDo lessons from Mr. Joe at age 5, that the experience has been great, that Mr. Joe’s teaching goes far beyond physical conditioning, and that their son has matured far faster than he would have without JSK TaeKwonDo. The same parent also described a family atmosphere, said their son is “hooked,” and noted that their daughter started at the school as well, ending with “Recommend!”
