Dennis grew up in Manitowoc, Wisconsin, where he began his musical journey at the age of six, taking organ lessons on a Hammond M2. However, during high school, he found himself feeling burned out on organ literature and made the switch to piano when he entered college. In 1989, Dennis graduated with a Music/Business/Audio Engineering degree from the University of Oshkosh.
Upon moving to Nashville, Dennis embarked on a thriving music career, quickly establishing himself as an in-demand session keyboard player. He had the opportunity to collaborate with numerous country music stars, including notable figures such as T. Graham Brown, Jimmy Hall of Wet Willie fame, Jack Pearson from the Allman Brothers Band, and Leroy Parnell. Dennis also toured with Delbert McClinton from 2011 until Delbert's retirement in 2021.
One of the pinnacle moments of Dennis' career came at the 62nd Annual Grammy Awards, where he clinched the Grammy for Best Traditional Blues Album for his work on "Tall Dark and Handsome" with Delbert McClinton.
Now retired and residing in the Stevens Point area, Dennis continues to share his musical talents. He maintains a studio and lends his skills to artists worldwide, providing overdubs that enhance their projects with his signature touch.
