Stephan was born in Grenoble, France, on June 8, 1976. At the age of 11 he began the saxophone at the school of music in Villefontaine, a small town
outside of Lyon. After graduating high school with a diploma in economy and sociology, he entered the department of jazz at the national school of music in Villeurbanne. He studied there until 1999 with the professors Gilbert Dojat and Jean Cohen.
At this time left for New York and the New School University, where he stayed for five years and obtained a BFA in 2002. During this period in New
York, Stephan studied with George Garzone, Billy Harper, Mike Karn, Junior Mance, Joe Chambers, Dave Glasser, Charles Tolliver and Doug Weiss. He
