Yes.
But don't take my word for it. Here's a few kind words from some lovely people I've worked with.
“I choose to bring Jamie in when the brief needs challenging, when the idea has to be big and when the work demands the most experienced and demanding of creative thinkers. From creating a brand identity for a hostage negotiator turned business listening guru, to communicating complex messages for City proxy solicitors, Jamie’s my man. He’s also good for a laugh, utterly reliable and I believe (having worked with many art directors and designers over the years) way too modest about his talents.”
