Danny Els

Associate, Member Services

Danny Els is a born and raised music nerd who has always held a special place in his heart for orchestral music. Despite having gone off to college at the Crane School of Music for a degree in Music Education – voice concentration, Danny was raised playing instruments throughout his childhood. These formative years as a young instrumentalist embedded a passion that carried through his undergraduate career. In fact, it was his passion for instruments that brought him to his decision to add a second degree in Music Business with an arts administration concentration.

After graduating in May 2016, Danny started working at the League of American Orchestras the following September. He now gets to enjoy his lifelong passion for music at work while also being on the front lines of the Member Services department. If you’ve ever got a login problem, he’s your go-to guy! This will be Danny’s third Conference during his tenure at the League. He looks forward to welcoming you all to Nashville this June for MUSIC CentriCITY! Come meet him at the check-in/registration table!

On a personal note, Danny loves to travel, cook, binge Netflix shows, and looks forward to marrying his partner David this November.
