Does this sound familiar?
✓ Waiting weeks for an appointment?
If it does…
you’re not alone. Healthcare has become rushed, impersonal, and frustrating for many people. Merlin Direct Primary Care was created to offer something different: the time, attention, and relationship every patient deserves.
Meet Dr. Ramón
Learn why I started Merlin Direct Primary Care and the kind of physician I strive to be for every patient.
It Starts With a Conversation
Before joining Merlin Direct Primary Care, every new patient is invited to schedule a complimentary Meet & Greet with Dr. Ramón Diez-Barroso, M.D., a board-certified family medicine physician serving individuals and families throughout San Antonio.
After completing his medical training at Baylor College of Medicine, Dr. Ramón founded Merlin Direct Primary Care around a simple belief: great healthcare begins with listening, building trust, and developing a lasting relationship with every patient.
Your Meet & Greet is an opportunity to get to know Dr. Ramón, learn how Direct Primary Care works, ask questions, and decide whether Merlin is the right fit for you and your family.

Wait… what exactly is Direct Primary Care?
Direct Primary Care is a membership-based model of primary care that creates a direct relationship between you and your physician. Instead of paying for each visit through traditional insurance billing, patients pay a predictable membership fee to their doctor’s practice for ongoing primary care.
This model allows the physician practice to focus on caring for a defined group of patients rather than managing each interaction as a separate billable event. The result is a different approach to primary care, one built around an ongoing physician-patient relationship rather than occasional visits.
Still not sure if it’s right for you, come in for a free meet and greet to learn more.
