In 1980, Erguner started teaching ney technique and theory at Istanbul University Turkish Music Conservatory. In 1981, he was accepted to work in the Istanbul State Radio and  Television as a ney player. In 1997, he completed his PHD on the history of Turkish mystical music at the Faculty Of Social Sciences at Marmara University. In 1995, he became the leader of Istanbul Mevlevi Ensemble (founded in 1980). Currently, Erguner is a faculty member at the Istanbul University Turkish Music Conservatory. He is also the conductor for the Classical Turkish Music Chorus and the Mystic  Music Ensemble of the Istanbul State Radio and Television. 

Süleyman Erguner  wrote and published a book about the techniques of playing the ney which is a first in the world.  He has given many solo concerts, joined many ceremonies performed by the mevlevi dervishes in Turkey and overseas since 1975. His CDs have received numerous awards in Europe, Japan and North America. His performance with the American conductor Lawrence Butch Morris in Istanbul and New York was hailed by critics as ground breaking and  released worldwide as a CD.

Erguner developed his own style sticking to the traditional modes while performing, but finding a new path trying to discover the best and never-tried way to express himself.  Süleyman Erguner continues his projects in a variety of formats: solo ney, classical ensemble (vocal accompaniment is an option); semi-classical ensemble with singers; sufi ritual with Whirling Dervishes; or mystic ritual with the Kadiri Sect (fifteen participants).  He is also the artistic director for  The Women’s Ensemble of Istanbul.
