Dennis Jeter began playing the trumpet at the age of 16 after attending a Wynton Marsalis concert in Washington, DC. Soon after, he was accepted into the Peabody Preparatory program in Baltimore, MD, to study with Wayne Cameron. In the spring of 1987, he graduated with honors from the Duke Ellington School of the Arts in Washington, DC. He later was enrolled as a computer science major at the University of Florida on a full merit scholarship. While attending the University, he participated in their marching band and held the principal trumpet chair in the symphony orchestra. In the Summer of 1987, Mr. Jeter received the first Wynton Marsalis scholarship to study music at the Eastern Music Festival in Greensboro, North Carolina. The following year, he transferred to the Manhattan School of Music in New York City, NY to study trumpet with William Vacchiano. While at the Manhattan School, his interest in the music industry broadened, and he soon became very active in the music business. In the Fall of 1990, Dennis was sponsored by William Vacchiano to become a Yamaha Young Performing Artist.

The groups performed regularly as a part of the Chelsea Concert Series founded in 1992 by Mr. Jeter to serve as presenter for the Consortium projects. In the Spring of 1991, Mr. Jeter graduated from the Manhattan School of Music to pursue a career in music performance. He has been presented in classical recitals throughout the United States as well as major jazz venues in the New York area, including the Miles Davis Tribute in 1992 at St. John the Divine, in which Mr. Jeter was a featured performer with the Max Roach Brass Quintet. In 1994 Dennis started the 'Monday Night Jam Session' at The Iridium in New York City, which ran for eight months.

While at the Iridium, Mr. Jeter began exploring the world of jazz through the eyes of a vocalist. This was to mark the beginning of a new era in his performing experience. The next few years were very rewarding. He had the opportunity to perform with the Lincoln Center Jazz Orchestra both as a vocalist and on the trumpet. Mr. Jeter began a weekly series at the Louisiana Community Bar and Grill in the Spring of 1996. In addition to his own quintet, Dennis featured over 25 of today's hottest jazz stars, including; Slide Hampton, Cyrus Chestnut, Joe Temperely, Vincent Herring, Carl Allen, Loston Harris, Marc Cary, Rodney Kendrick, Paquito Di Rivera, Wes Anderson, Milt Grayson and many, many more.
