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. Amanda Montford, President, Savannah Drywall Supply, Inc. **Member since 2000** --- ## Divisional Highlights [ALL NEWS FOR THIS DIVISION](https://adhq.com/about/ad-news?industry_id[]=292) [](https://adhq.com/about/ad-news/ad-names-2026-llc-board-of-directors-following-owner-member-vote) [AD Names 2026 LLC Board of Directors Following Owner/Member Vote](https://adhq.com/about/ad-news/ad-names-2026-llc-board-of-directors-following-owner-member-vote) March 31, 2026 [](https://adhq.com/about/ad-news/l-k-l-associates-inc-expands-with-acquisition-of-steel-connections-inc) [L.K.L.
