  • I would advise a strong, independent distributor to join AD. AD is a very discriminating organization. If they're talking to you, if they're interested in you, it means great things. It means that you're a leader in your market; it means that you're financially stable, it means you're well respected. When we're working with an AD distributor, we know they've already been pre-screened, that they're going to be a successful distributor, and that they're going to be worth our time.

    Henri Jung, COO, Phillips Manufacturing Co. Supplier Partner since 2012
  • Access and support from the high-level executives from our supplier partners has made me a stronger business owner. That's not something that I ever would have had without AD, because as a small business, you don't always get to go sit down with the president and the CEO of a huge national – or sometimes international – corporation. Through AD, I've been given that opportunity to meet and develop close relationships with a lot of these people, and that has been very valuable for us.
