Drew McLellan has worked in advertising for 25+ years and started his own agency, McLellan Marketing Group in 1995 after a five-year stint at Y&R. He also owns and runs Agency Management Institute (AMI), which serves 250+ agencies small to mid sized agencies and is the host of the Build a Better Agency Podcast. I sat down with Drew to get an ad industry veteran's perspective and to better understand why he choose it as a marketing channel for growing his business.
