Matt and Kerry recruited Jeff on Bass in March 2009 and the trio quickly became a staple in the Denver music scene. Jeff met Matt a few years earlier, working at the same local advertising agency where Matt did his college internship.

Jeff has been playing the bass for over 15 years. He played in several heavy metal bands prior to joining the Matt Nasi Band. Despite the genre flip, he still brings his "gruff" attitude to his bass playing. His musical inspirations include Steve Harris, Geddy Lee and Flea.
