If there's one thing that any modern accounting firm knows, it's that people can't be bothered to utter the names of long-dead founders when they refer to your organization. Hence the trend of rebrandings that trade ampersands and/or 3-4 names mashed together in no discernible order for 2-4 initials.
As far as branding goes, there is either beauty in the simplicity or the sheer laziness. I can't really decide which it is.
Regardless, you may now add Dixon Hughes Goodman to this list of firms throwing in the towel on their dead founders' names. The firm slimmed down to DHG back in January and we're just now hearing about it, which is fine.
Like other firms who have made similar changes, the firm is still legally Dixon Hughes Goodman because, crikey, no one wants to go through the trouble of changing that.
