Pros
I've knew Athlon before joining - they were my chosen provider when I was a director for a larger agency. I whittled our 12 providers down to 3. Athlon being the first choice. So when I was approached to join I jumped at the chance and haven't looked back. They are the first agency who got "design thinking", and tried whenever possible to turn a project from a process to a creative and strategic solution (when clients allow). This has lead to some great projects, hires and a vibe that treats staff like people not robots. I've felt part of the growth and learnt and enjoyed that journey - including the challenges. If was easy we'd all be doing it!
Cons
With growth come the pains. A couple of bad clients and wrong employments; but lessons have been learnt, and in the 3 years I've been here only 1 employee has decided to move on. This for me is a sign of a place people want to work. I for one don't have the Sunday evening dread!
