Member of the Month: Diana Medina Galvan, MD

For Diana Medina Galvan, MD, family medicine has always been about building meaningful relationships and delivering truly patient-centered care. After years practicing in traditional clinical settings, she developed a deep appreciation for comprehensive primary care while recognizing the challenges that time constraints and administrative demands can place on the physician-patient relationship. That experience inspired her to launch Luminous Health and Wellness in 2019, a direct primary care practice in Houston designed around longer visits, greater access, and personalized care. Today, she combines her expertise as a board-certified family physician and obesity medicine physician to help patients improve their overall health, with a special focus on metabolic health and perimenopause and menopause care. 

Who or what inspired you to become a family physician?
Family medicine appealed to me because it combines breadth, continuity, and trust. I was inspired by the idea of being the physician who can care for an entire family across seasons of life, and who can partner with patients over years, not just a single visit. I also valued the ability to blend preventive care, chronic disease management, and lifestyle-based medicine into one specialty.

Congratulations on opening your own private practice! How is it going?
It has been both challenging and deeply rewarding. Building a clinic from the ground up taught me to be intentional about the kind of care I wanted to deliver, the systems that support it, and the community I wanted to serve. I am proud of the patient relationships we have built and the outcomes we are seeing, especially when patients feel heard, supported, and empowered.

What are your practice passions?
My passions include prevention, metabolic health, obesity medicine, and caring for women through perimenopause and menopause with evidence-informed, individualized treatment. I also care deeply about patient education, helping patients understand their bodies and options, and creating a clinical environment that is calm, respectful, and judgment free.

You are building a social media following as a family doc. What made you begin that journey? 
I started because I realized many patients are getting health information from social media, whether we participate or not. I wanted to provide clear, evidence-informed education in a way that is approachable and empowering. It has also become a way to advocate for patient-centered care, normalize conversations around menopause and weight stigma, and help people understand that family medicine can be both comprehensive and highly specialized in areas like metabolic health.

Why do you choose to be a TAFP member?
I value being connected to a professional community that advocates for family physicians and patients across Texas. TAFP helps ensure that the voice of family medicine remains strong. I also appreciate the opportunity to connect with colleagues who share a commitment to excellent, broad-scope care.

What do you enjoy doing outside of medicine?
Outside of medicine, I enjoy spending time with my family, crafting, listening to podcasts, and being involved in community activities.
