Dendy started drumming at the age of 10. Although he had a natural talent for rhythm, he credits his parents as well as his band director, Jim Mills, with his early "sticktoitiveness." He was awarded the honor of the John Philip Sousa Band award at his high school graduation. College brought a more serious pursuit as a percussion performance major at the University of South Carolina under the tutelage of Jim Hall (former North Texas instructor whose students included Rick Latham and Gregg Bissonette.) There he studied drumset and timpani performance. During this time Dendy performed as a quad player in the SunCoast Sound Drum & Bugle Corps 1983/84 Season, where they finished in the top 6 in the world. Shortly after that he accepted a position as the touring drummer with the group The Foundations, a gold record artist whose hits included “Build Me Up Buttercup” and “Baby Now That I Found You” (later re-released by Alison Krauss).
His music instrument retail career includes the positions of Manager, Paragon Percussion Center in Tampa, Florida, and General Manager of the 35,000 square foot Thoroughbred Music Center in Nashville, Tennessee.
As he transitioned to the music instrument industry, Dendy served as Director of Marketing and Artist Relations at Mapex Drums and Slingerland Drums. He was in charge of Slingerland's operation during his last year with them. He also served as Director of Marketing for Natal Drums, a division of Marshall Amplification, when they launched the new line in the United States. During his various positions within the industry, Dendy has cultivated valuable and long-lasting relationships with many artists and peers.
As the Web took the MI industry by storm, Dendy forged an online presence with time spent at GearGate.com and MarsMusic.com. In August 1999, he joined United Entertainment Media's Music Player Network as editor and content manager for the Drum Channel.
When the Music Player Network was dissolved, Dendy, along with industry titan Craig Anderton, were the only survivors when the Music Gear Network took over the web operation for UEM. Dendy continued to oversee the web operations for Guitar Player, Bass Player, EQ, and Keyboard magazines, as well as the Music Player Network Forums until 2005.

It is the only hip music magazine that includes a curriculum for the classroom.
