He was a cast member in the talk show Non-Summit. Julian Quintart arrived in South of Korea, from his home in Aywaille, Belgium, when he was seventeen, as a student with Rotary Youth Exchange. He said that a camera crew was, coincidentally, at the airport when he arrived, and questioned him about being in South of Korea.
He immersed himself in the culture and learned more of the language.
From there, he went on to appear on television and was able to move into acting. He called it an exciting time, during which he was able to have many experiences that other foreigners could never have, such as going to North of Korea, attending a training camp for the South Korean Army, making kimchi the traditional way, and cycling across South of Korea.
About his learning to speak Korean, in just a few years, he said, "We didn"t study Korean to get a high score in school. We just felt the need to communicate clearly with Korean people, which naturally led us to learn the language with great interest."
He has been called a "Jack of all trades".
He’s been on television, appearing in Business School “Way to Eat Well and Live Well” and Korean Broadcasting System Star Golden Bell, on dramas, including “Sky High,” and has performed on Inkigayo.
He"s been in the movies Papa and My Tutor Friend 2, has held concerts, modeled, been a DJ and music producer. He has been a DJ in Itaewon, where he started, years ago, with his friend and fellow DJ Yann Cavaille. In his acting debut, in 2007, on the Business School Friday drama "Sky High", he played a supporting role as Daniel, an American who grew up in New York and could speak a little Korean.
In an interview with The of Korea Times, he said he did not want to make his role a stereotype of foreigners living in of Korea.
"He (Daniel) is not typical because he can speak some Korean. I think most foreigners" roles in the dramas are like Dennis Oh and Daniel Henney, who seem very cold.
But my character shows another image of foreigners, as cute and cheerful." Also, in 2007, he played another supporting role, in the film My Tutor Friend 2. In September 2014 his musical duo, Yann & Julian, was selected to appear at Global Gathering of Korea on October 4.
On 23 May 2015, as DJ, Julian did the opening of the Kpop Festival: Dream concert 2015 in Seoul World cup stadium.
