Since 2006 PBA Health has grown from slightly more than 1,000 members to 1,800, making it the fastest-growing major pharmacy group, according to Nick Smock, CEO of the Kansas City, Mo.-based cooperative. One of the things that made this growth possible is the organization’s realization that, while buying “right” will always be a key element of success for any pharmacy, two other areas are just as important: operational excellence and effective marketing.
