Who We Are

Sully's is a family-owned company run by Mike & Davanne O'Sullivan. Prior to getting married in the Fall of 2014, Mike simply ran the company from wherever he was living at the time. Over the last 10 years, this has included Chicago, IL; Milwaukee, WI; Rosebud, SD; and now, Mobile, AL.

Mike (aka DJ Sully)
Hailing originally from a suburb of Chicago, Mike began deejaying alongside a friend of his at the age of 15. After a few years, Mike began deejaying on his own and continued to do so throughout his college career. From 2010-12, Mike moved to South Dakota to volunteer and work among the Lakota people. While there, he worked at a local radio station, hosting and producing his own weekly show, as well as working as an on-air personality. 

In his 10 years in this business, Mike has enjoyed deejaying in venues ranging from local VFWs to world-class facilities like the Willis Tower and the Shedd Aquarium. He has played for crowds as small as 20 and larger than 1,000. 

Davanne (aka DJ D)
Davanne is an Alabama native new to the DJ scene. She is the country music expert on staff and assists in various roles from booking to event. 

Our History

Our little company has come a long way since it began back in 2005! 

The very first event we ever deejayed was a backyard graduation party. (We didn't even own a car yet!) Since those humble beginnings, we have served thousands of happy party goers with our ever-growing music library, professionalism, and fun personalities (if we may say so ourselves).
