Alex Dempsey is from Wantagh, New York where his musical journey began. Starting his musical career as a drummer and guitarist, he spent a lot of his early life taking lessons and training to be a musician before getting involved with audio. After getting invited to attend a recording session at Five Towns College with the professor of Audio Recording Technology, his pursuit of becoming an audio professional began. 

During his time at Ithaca College, Alex's professors and classmates inspired him to work hard and to expand his knowledge. The Audio Engineering Society chapter at Ithaca College exposed him to more opportunities to grow his knowledge. As an engineer at the Aspen Summer Music Festival and school, Alex got valuable exposure to working with engineers from all over the country with many different backgrounds and skills. From all of the generous mentoring he recieved, Alex wants to work with others and give back to the community that he loves.

Whenever he is not doing audio work, Alex enjoys working out, watching movies and hanging out with friends.
