Corey Peterson is the founder of COS Celebrations and has performed at over 1,000 weddings across North and Central Florida. A professional touring musician who has shared the stage with T-Pain, Alicia Keys, Usher, and Slightly Stoopid across 40+ countries, he brings a level of musicianship and crowd-reading instinct that most DJs simply cannot match.
Most wedding DJs got into the business through events. Corey got into it through music. He started on piano at age four, picked up saxophone shortly after, and spent years touring professionally - performing on stages across six continents and sharing lineups with some of the biggest names in music.
That background changes everything about how he approaches a wedding. Where other DJs rely on pre-built playlists and hope for the best, Corey hears a room the way a musician hears a band. He knows when the energy is building, when it needs to breathe, and exactly when to push it over the edge. It is not a formula - it is instinct built from thousands of hours performing live.
He founded COS Celebrations with his fiancee Kyle, and together they pioneered the DJ + live saxophone model in Northeast Florida. The concept was simple: what if a wedding DJ could actually play music, not just press play? That idea became the foundation of everything COS does.
Today, Corey leads a team of DJs and musicians across Jacksonville, St. Augustine, Ponte Vedra, Amelia Island, Orlando, and beyond. He still performs regularly - because after 1,000 weddings, the dance floor still gives him a rush. But he also spends time training every DJ on the COS roster, making sure the same musicianship and attention to detail shows up whether he is behind the booth or someone else on his team is.
Every couple is different. Every wedding should feel different. Corey builds each set around what the couple actually wants to hear - their songs, their energy, their vision for the night. There is no default playlist. There is no template. The first conversation is always about you.
This is the part most DJs struggle with and where Corey's touring background becomes an unfair advantage. After performing for crowds of 50 and crowds of 50,000, reading a room is second nature. He knows when to bring the energy up, when to let a moment sit, and how to keep a dance floor packed without forcing it.
No TV screens on the booth. No flashy ego-driven setup. No over-the-top MC voice competing with your night. Corey's philosophy is to remove all ego from the day and keep the focus where it belongs - on the couple and their guests. You should not notice the DJ. You should notice that the dance floor is packed and you are having the best night of your life.
When live saxophone weaves through a DJ set, it creates something recordings cannot replicate. The energy shifts. People stop checking their phones and start moving. This is not a gimmick - it is what happens when real musicianship meets real-time crowd connection. It is the reason COS exists.
CO2 cannons can be fun. Cold sparks look amazing. But the foundation of a great wedding is the music and the moments. Corey does not need a bunch of toys to make a dance floor unforgettable - he needs the right song at the right time and the instinct to know the difference. The extras are extras. The music is everything.
"Corey was hands down the best vendor decision we made. He listened to exactly what we wanted, nailed every song transition, and kept the dance floor packed from the first dance to the last song. People are still texting us about how fun the reception was."
"The live saxophone during the reception was something our guests had never experienced at a wedding before. Corey read the crowd perfectly and the energy was unreal. We did not want the night to end."
"We trusted Corey completely with the music and he delivered beyond what we imagined. No cheesy DJ voice, no awkward announcements - just perfect music and a dance floor that never emptied. Exactly the vibe we wanted."
"From our very first call, Corey took the time to understand what mattered to us. He asked the right questions, gave honest suggestions, and on the wedding day he made it all come together seamlessly. Worth every penny."
"Our planner told us Corey was the best DJ she works with, and after our wedding, we understand why. He coordinated everything with our other vendors, kept the timeline on track, and the music was flawless. Our guests are still talking about it."
"Corey played saxophone live during our cocktail hour and DJ'd the reception. Having one person who is both a real musician and a DJ made our whole evening feel connected and intentional. COS Celebrations is the real deal."
Corey has performed at premiere wedding venues across North and Central Florida. Here are a few favorites.
