TDA and America’s Physician Groups (APG) are combining forces - bringing every APG member organization, and every practice within them, into the country's largest independent-practice vaccine buying and medical purchasing group. Same ownership. Same clinical autonomy. More leverage at the negotiating table.

The strength to thrive. The autonomy to stay independent.

Trusted Doctors Alliance is a purchasing alliance built for independent practices and the organizations that support them. Joining TDA puts your practice inside a group that negotiates directly with vaccine manufacturers and medical vendors and secures pricing no single practice can get alone.

And beyond pricing, we're building a community of independent practices that acts collectively to advocate for you - protecting your ability to compete and stay independent as the industry consolidates around us.

For Independent Practices

You Fought for Independence. We Help You Keep It.

Gain immediate access to premier vaccine contracts, aggressive group purchasing discounts, and essential operational resources that optimize your bottom line - while keeping complete control in your hands.

  • You Are Not Alone

    Tap into a collective, powerful voice dedicated to advancing and protecting the interests of independent practices — wherever they sit in the healthcare landscape.

  • Leadership that Understands

    “Our leadership were — and still are — independent medical practice leaders. We built Trusted Doctors Alliance so independent practices would have a place to share a common goal and exchange the ideas that help each one thrive.” Dr. Sandy Chung, Past AAP President

What Membership and Partnership Looks Like

  • Enrollment gives your practice access to the reduced pricing of our Vaccine Buying Group — with contracts across GSK, Merck, Pfizer, and Sanofi — securing thousands of dollars in savings, even for small practices.

    We've also curated select vendors with unique pricing you won't find elsewhere, on the services and goods that cost independent practices the most — like strep and flu testing.

  • A clinical lead is available to meet with you and help select the vaccine products and pricing that best fit your practice's needs. Your account manager is also on hand to answer questions and help you enroll in products you already use or are looking to add.

  • Once a practice signs up, you get access to your own portal — showing you the contracts and products you already have, while also letting you explore new products and self-enroll.

  • You are not alone — hundreds of other practices are already members. We're building a space where you can share ideas, ask questions, and exchange resources with one another.
