Living Out Faith Through Medicine and Sacrifice

For Dr. Marco Chalaby (BA ’87, MA ’89), what once felt like a serendipitous decision to leave Rome for Baylor ultimately revealed itself as part of God’s greater plan.

Arriving in 1983, he pursued English and pre-med while deepening his love of music through piano. He spent time working in the Armstrong-Browning Library, even cataloguing Robert Browning’s handwritten letters, while also building lifelong friendships.

Though he wrestled with questions about Christianity during his college years, the influence of Baylor’s community and coursework planted seeds that would later grow into a deep and lasting faith.

Today, as a pulmonologist and critical care physician in San Antonio, Dr. Chalaby lives out that faith in extraordinary ways. When a longtime patient and friend faced a life-threatening illness, he stepped forward as her living organ donor—saving her life and turning friendship into family. He hopes others know it’s possible to live a full, healthy life as a living organ donor.

Looking back, he credits Baylor with shaping the person he was meant to be—one defined by excellence, faith, and sacrificial service.
