About COS Celebrations
COS Celebrations is Northeast Florida's premier wedding entertainment company, founded by Corey Peterson. What sets them apart is their signature DJ + live saxophone combination—Corey pioneered this concept in the Southeast and was featured as a "Trendsetter" by Southern Bride Magazine.
Before launching COS Celebrations in 2022, Corey toured internationally as a saxophonist with artists including Usher and Alicia Keys—performing in over 30 countries. That stage presence and ability to read a crowd translates directly to wedding receptions.
Corey leads a team of professional DJs who each bring their own energy while keeping the company's high standards. Whether you work with Corey, CJ, Greg, Noah, or Marc, you're getting someone who knows how to keep guests dancing and handle the flow of a wedding day.
COS Celebrations was also named Best DJ Company by Jacksonville Magazine.
Why We Recommend COS Celebrations
We've known Corey for over two decades — long before the wedding world, back when he was touring as a world-class saxophone player. When he moved into weddings, he came at it as a musician first: he looked at the experience couples were having and saw a way to elevate it, a hybrid DJ-and-live-music show unlike anything else out there.
When he first described it to us, we thought, sure, that sounds neat. Then we saw it in person — holy cow. At Ashley and Craig's wedding, the reception started off normal, music playing, and the next thing you know cold sparks are flying through the air and Corey comes bursting out with the saxophone. It turned the whole reception into a concert.
What Corey does so well is match the couple's expectations with the energy he brings. Some couples want to keep it low-key; others want a rager. Twenty-plus years as a live performer have given him the instinct to know exactly when to turn it up and when to pull it back — and somehow always keep the focus right where it belongs: on the couple. It's a delicate balance, and he nails it every time.
What Couples Say: COS Celebrations Reviews
5★ across 500 The Knot & WeddingWire reviews
With 500+ five-star reviews across The Knot and WeddingWire, the feedback is consistent: COS makes the entire experience seamless. Couples mention how great the communication is during planning, how perfect the music selection was for their crowd, and how Corey's saxophone made the night unforgettable.
We hear it from our own clients too. After the wedding, the thing couples rave about most (besides the photos) is usually the DJ. When COS is on the lineup, we know the reception is going to be great—which means better candid moments for us to capture and a dance floor full of energy all night. They make the whole evening feel effortless, and that's what makes them perfect for couples who want a packed dance floor without the cheesy DJ vibe.
