Corey Peterson
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.
We've done 2,000+ weddings with 500+ five-star reviews, but what I'm proudest of is the team we've built. Every DJ and musician here gets it - no egos, just people who genuinely love making your day perfect. We treat every wedding like it's the only one on the calendar. Your vision, not ours. Starting at $1,500 with live saxophone available. Tell us about your wedding and we'll be in touch within 24 hours.
What St. Augustine Couples Say
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. We feel so lucky to have worked with them and will absolutely be using them again for future events.
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. The music, the vibes, the transitions - everything was flawless. If you want a DJ who truly elevates your wedding and creates an unforgettable party, Corey is your guy.
We had the absolute pleasure of working with Corey as the DJ for our daughter's wedding, and we couldn't be happier with the experience. From the very beginning, Corey was organized and professional, making the entire music selection process so easy in what can often feel like an overwhelming decision.
Our wedding planner even noted that Corey was the only vendor who proactively reached out to review the timeline with her, ensuring that every detail flowed seamlessly-and it truly did. As an MC, Corey was outstanding. He kept the evening moving effortlessly, keeping our guests informed and engaged from the ceremony all the way to the final dance.
On top of his professionalism as a DJ and MC, Corey is an incredibly talented saxophonist. Many of our guests commented on how amazing the live saxophone music was and how much it elevated the entire evening.
With the support of his assistant, Noah, every transition throughout the night was flawless. Music has the power to both reflect and create the mood, and Corey did exactly that-he created an unforgettable, joyful atmosphere that made our daughter's wedding night truly memorable.
We cannot recommend Corey highly enough!
Why St. Augustine Couples Choose COS
We're Actually Local
COS Celebrations is headquartered in St. Augustine - this isn't a satellite market we drive to. We know which venues have tricky load-in procedures, which historic buildings require careful sound management, and where to find parking on busy downtown weekends. That local knowledge shows.
