Anyone can say they are a DJ. Simply owning a computer and some speakers does not make you a DJ. They now sell DJ-In-A-Box, lol!
There is no certification or license vocation for Professional DJs. One test is to compare years of DJ experience, as well as years of experience in the wedding and event industry. How long have you been a DJ? How long have you been in the wedding industry? How many weddings do you typically perform for in a year? Can the DJ answer questions about your program, song selection, vendor recommendations? Do they have the ability to read the room? And the musical prowess to manipulate the room?
Each Kustom Sounds Kauai DJ is personally trained by Owner, Michael Dandurand who has been DJing weddings and events since 1986. He has personally performed well over 4,000 events in his successful career.
