Drew Bartholomew, President of Vetcelerator, joins the Veterinary Ledger Podcast to break down how veterinary buying groups and GPOs actually work. He explains collective purchasing power, vendor alignment, rebates, compliance, and the economics behind supplier negotiations. The conversation explores common misconceptions, transparency gaps, inventory management red flags, and whether practices should join multiple groups. Drew also discusses the complexity of lab contracts, rising supply costs, and how independent animal hospitals can stay competitive. The episode offers practical questions that practice owners can ask today to evaluate savings, refine procurement strategy, and strengthen cost control without sacrificing operational flexibility.
