  • Steve Kelly
    After using TAG, I now understand the difference. I’ve used other auditing companies before and the added benefits and thoroughness that TAG incorporates into their process is why I continue to use them exclusively.

    Director of Disbursements, Hospital of the University of Pennsylvania
  • Steve Patton
    In my last two positions, being responsible for supporting large acute healthcare systems and ensuring that we have sound practices and processes in place, I truly needed a team that would not sugarcoat how we were doing, help us improve our processes, and mostly help me recover that money. TAG does what they say they are going to do - thoroughly.

    Director of Supply Chain, Lakeland Regional Health
  • Jim Haddock
    We’ve used other vendors in the past, but none even came close to matching TAG’s professionalism, detailed analytics, customer service, or results.

  • Pam Buda
    I have never felt so positive regarding a service as I did with [TAG]. They were very considerate of my time, approachable, and knowledgeable. The services they provided were invaluable. As a new manager, they offered many ideas and much feedback. Great job.

  • Catherine Wakefield
    I was impressed with the approaches TAG has developed over the years. This allows them to focus on areas of high return for an organization while helping AP personnel improve their processes to minimize errors and duplicate payments.

  • Mark Combs
    I have worked for several organizations that have engaged [TAG] to perform various functions and am always impressed with their well-seasoned and professional staff. Results have always been outstanding in large part due to the professionalism and diligence of the staff.

  • Keith Van Fleet
    My AP and Purchasing departments are short-staffed. Said simply, TAG does the things that my department cannot tackle at this time, and it’s so reassuring to have them in our corner to monitor our accounts.

    Director, Accounting and Reporting, Atlantic Health System
  • Douglas B. Butt, CPA
    [TAG] made it a painless process. They know the healthcare business, they know the suppliers, and they know the stones to overturn looking for overpayments, duplicate payments, or a payment not according to contract. They are like an old, reliable employee whom you call upon to help you out. You can’t go wrong with TAG.
