By Rob Nance, AccountingWEB PublisherThe first Association for Accounting Marketing (AAM) annual conference I attended was in 2001 in Toronto. Last week's gathering in San Diego was a stark contrast. Oh, sure, some things haven't changed, such as few CPAs in the mix. These conferences are outstanding opportunities for a firm's managing partner to accompany the marketing director they are sending. Hopefully, someday that will be the norm rather than the exception.Just as marketing, business development, and public relations have grown within our industry, AAM has grown too.
