About
Sebastian A. Guzman is the author of Elias Wynn: The Witness, his debut novel.
He is drawn to stories about suffering, trauma, healing, faith under pressure, and the hard questions that surface when life stops making sense —and the resilience that pulls us through. His writing is shaped by his Christian faith, his background in neuroscience, and his time working in and around medicine as an EMT.
Before writing The Witness, Sebastian was studying neuroscience while working, serving in his church, and preparing for a future in medicine. He was nearing the final stretch of his undergraduate journey when illness interrupted the life he had been building.
In January 2025, he was diagnosed with granulomatosis with polyangiitis, formerly known as Wegener’s disease, a rare autoimmune condition that forced him to step away from work, school, and many of the plans he had been pursuing. That season of illness, recovery, therapy, and spiritual wrestling deeply shaped the emotional world of his debut novel.
For Sebastian, fiction became a way to wrestle honestly with fear, weakness, suffering, faith, and the longing for healing without pretending those questions are simple.
He lives in Rhode Island with his wife, Ana, a registered nurse.
While his writing explores the hard questions of faith under pressure, it ultimately seeks the light that remains when life stops making sense.
