“After an amazing 10 years at Atomic 212°, I’ve achieved so many goals and had so much success. I’m looking forward to having more time to focus on my family in my next adventure. It’s a decision that doesn’t come lightly, as I have come to consider many members of the Atomic 212° team family. We’ve had a phenomenal journey together and achieved unmatched success. I’m incredibly proud to be leaving Atomic 212° as the number one independent media agency,” said Fenner.
“Thank you to all the brilliant, talented people in the business and, in particular, the incredible senior leadership team who have all played an instrumental role in the success of Atomic 212° and the success of our client partnerships”.
