What is Direct Primary Care?

Direct Primary Care (DPC) is a modern approach to healthcare that removes insurance from the doctor-patient relationship.

Instead of billing insurance for each visit, patients pay a simple monthly membership that covers most primary care services. That means:

  • No copays
  • No surprise bills
  • No rushed appointments

At our San Antonio Direct Primary Care clinic, you get direct access to your physician, longer visits, and care that is focused entirely on you, not insurance requirements.

How is DPC Different?

Traditional Primary Care:

  • Insurance-driven care
  • Short, rushed visits
  • Limited access to your doctor
  • Unpredictable costs

Direct Primary Care:

  • Membership-based care
  • Longer, unhurried visits
  • Direct phone/text access to your doctor
  • Transparent, upfront pricing

Why Patients Choose Direct Primary Care

Patients choose DPC because they want:

  • More time with their doctor
  • Easier access to care
  • Clear, predictable costs
  • A real relationship with their physician

Patient Reviews

Herman Romero

I truly appreciate the same day appointment option. I would definitely recommend.

Dawn Campbell

Dr Ramon Diez Barroso is the first person I| want to call about any question on my health or for my loved ones' health. His intentional way of listening and wanting to make sure he understands what you are feeling, makes me feel very good about his diagnosis. He has been 100% right on the mark and knows exactly what to do to make things better. Thank you

Travis Swisher

I came in thinking I had an eye infection because my eye was red and irritated, but it turned out to be a scratched eye. Doctor Diez-Barroso was very calm, thorough, and reassuring. He explained what was going on clearly and let me know it would heal on its own in a few days, which it did. I appreciated that he didn’t push unnecessary treatments and instead gave honest and helpful advice. Great experience overall!

Dr. Marcus Cavazos

Adriana Casso

After battling breast cancer, I faced many lasting challenges from chemotherapy and other treatments. I saw several doctors, but none felt like the right fit for my complex case—until I found Dr. Diez Barroso. When I called, he personally answered and took the time to truly listen. His kindness, attentiveness, and clear explanations gave me hope for the first time that I could have a family doctor who understands my needs. I am deeply grateful to be under his care
