Our Story

Care designed around you. Built with purpose.

Luminous Health & Wellness was founded on a simple belief: that every patient deserves a doctor who truly listens, who remembers their name, and who shows up for them as a whole person.

Tia Minerva

The woman who saw right through me

The Luminous butterfly is not just a brand mark. It is a tribute to a woman who believed in Dr. Medina before she believed in herself.

Minerva

There are people who influence our lives and deeply change us for the better. One of those people was my aunt Minerva. When I was young, my parents worked multiple jobs. Tia Minerva would help take care of me and my younger brother while they were away.

“Get over here! Look me in the eyes,” she’d say. She’d get real close and whisper, “I see a little horsey running across your eyes. You’re lying to me.” I would run to the bathroom mirror to see the horsey for myself. That dang horse was always giving me away.

In 2012, I was in my second year of residency at Houston Methodist Hospital, one of four residents chosen to continue training at a globally recognized institution. I was learning from global leaders in medicine. And I was ready to quit. By this time, my beloved Tia Minerva had been in the hospital for months.

“Dianita, tú has nadado por aguas profundas para ahogarte en la orilla del mar.”

“You’ve swum across deep oceans to come drown in shallow waters.”

Tia Minerva

She believed in me more than I believed in myself. It is her words that gave me the strength to finish. My aunt passed away one month after that visit in the hospital.

The Meaning Behind the Logo

Every detail was chosen with intention

The butterfly

Tia Minerva loved butterflies. She was strong, brave, and packed a lot of punch in a small package. The butterfly is her spirit, and the spirit of this practice.

The two faces

The butterfly is drawn as two faces looking at each other. Her eyes looking into mine. A reminder of the woman who saw the truth in Dr. Medina before she could see it herself.

The colors

The colors are those of the ocean, the crystal blue-green waters that recharged Dr. Medina’s soul during medical school. The ocean she almost let herself drown beside.
