I live here. Moved away a couple times, always end up back — St. Augustine is home. It's where family's at, where we built COS from the ground up. I spent years touring 40+ countries, sharing stages with artists like Usher, Alicia Keys, and T-Pain. Then I stepped away from music for a while — nice house, good paycheck, but something was missing. Hadn't touched my horn in years. A buddy dragged me to a jam session on a Wednesday. That night I met a Grammy-winning producer who's now a dear friend — and that conversation changed everything. By Monday I'd walked away from all of it to get back to what actually matters.
First wedding I did changed everything. Being part of someone's biggest day — nothing compares. Now I've been working St. Augustine venues for over a decade. Treasury on the Plaza, Lightner Museum, River House, Fountain of Youth, Tringali Barn, Kelly Farm, 9 Aviles — I know where the sound gets tricky, where to park when downtown is chaos, which coordinators run a tight ship. That stuff matters when it's your day and you don't need surprises.

What Do St. Augustine Couples Say About COS?
Words can't describe how special Corey and his team made my husband's and my wedding day at the Lightner Museum in St. Augustine. Being from Boston, this was a destination wedding, and Corey and Kyle put us at ease every step of the way. Any questions we had were answered right away and very thoughtfully, which truly gave us peace of mind.
Corey made every single moment so special for us - he even played the sax during our entrance song, and it got the crowd going wild! We will truly never forget these moments and can't recommend COS Celebrations enough. Corey is hands down the best DJ we could have ever asked for. He read the room perfectly, kept the energy high all night, and had every single guest on the dance floor.
We were lucky enough to book COS Celebrations and DJ Corey for our NYE wedding at the end of 2023. Corey immediately came across as an organized and reliable professional that knows how to have fun! He was extremely communicative during the days leading up to and during our wedding, always making sure we were taken care of and having a great time.
We opted to add the Saxophone add on and it was INCREDIBLE. Everyone loved it and really got the party pumped up for NYE. We also booked his extra lighting, cold sparklers and photobooth - everything was so great and really completed the event. I could not recommend Corey enough; he made our day so special and provided a top-notch service.
Corey is the best. It was an incredible night and the dance floor was never empty. He is genuine and a great person to work with. We trusted him wholeheartedly to put together a song list that matched with who we are as people. The saxophone during Cocktail Hour was exceptional and he was able to work in a few Billy Joel songs to keep the Long Islanders in attendance happy.
He was organized and utilized an app that allowed us to easily fill in song requests, first dance songs, last dance songs, etc. so that the night was all about what we wanted. We also loved the personalization for the photobooth background that Kyle put together for us featuring the St. Augustine Lighthouse. You can't go wrong with COS Celebrations.
